Every year we have transitions in product lines and collections and, in most cases, these changes are evolutions. Changes are as minute as a different topsheet material or maybe a lighter core. Changes we will discuss here are revolutions to the point that a brand will not only start with a clean sheet of paper or a new CAD screen but in most cases completely throw away an established model name to start fresh. The skis in this article are all completely different from the models they replaced. Like in our Cage Matches, we are not saying this is good or bad, but different. What you thought you may have liked or disliked about the outgoing model will now require a completely fresh take to decide if the new model is or is it not what you are looking for in a ski.

We will start alphabetically with some of the models or collections that are 90° to 180° departures from the models they replace. I will talk about the attributes from the outgoing model and what to expect from the new one. From there you will need to decide if you want to start scouring the clearance racks and discount sites or think, “They finally got it right! This is what I have been looking for all along.”


Out with the Invictus and in with the Declivity series. This change happened for a few reasons. First, the Invictus series was around for a solid time frame and was getting long in tooth and second, with Armada coming under the Amer umbrella and bringing their ski building in house, they had a chance to change gears. So, out with the Invictus, a line that has received numerous awards from our testers, and in with the Declivity line. The Declivity series has a much more balanced shape than the Invictus which was a hybrid of a few of their past collections. That worked well together but the Invictus were almost binary in on-snow feel. Some felt they were either on or off. The new Declivity tip is relaxed and gradual into the turn and the tail locks in. The Declivity has a playfulness and balance that the Invictus was missing.
  • What you will miss: Power and a solid finish of the turn​
  • What you will gain: A more centered feel on a playful ski​
  • Insider tip: The women’s Victa is still in the line, expect the same revolution next season.​

There is no question the Blizzard Bonafide and women’s Black Pearl 88 (and 97) are recognizable skis, and are the skis in their respective categories to which all others are compared. To make a revolutionary change to skis that have had this much success is always a risk. Did Blizzard do the right thing? Well, the outgoing model of both the Bonafide and Black Pearls were the epitome of those “old comfortable jeans." They just worked. They were tried and true, even through their slight evolutions over the past decade. For this season Blizzard abandoned everything we have come to love with these skis including the tried and true lengths in which they were offered. Where before if you matched up with the offerings, great. Conversely, if you fell between sizes, game on. Out is “Flipcore” and in is a entirely new scaled core design that takes the size of the ski skier into account. The new Bonafide and Black Pearl 88 and 97 are much more serious in feel and not as forgiving as their predecessors. Where you could put almost anyone from a solid intermediate with a reasonable skill set on the old versions, the new ones are more for the advanced/expert skier. Remember back in the 'Future Products We Would Like to See' thread we asked for a high performance version of the Black Pearl? Well, this is it.
  • What you will miss: Compliance and playfulness​
  • What you will gain: Strength, better scaled sizing​
  • Insider tip: Check sizing, these do ski true to their new lengths.​

For 2021 Dynastar abandoned the extremely adequate Legend series for the M-Pro/M-Free collection that has more of a backbone to it. This is where this article grew legs: the change that Dynastar is making in the very important All-mountain/freeride segment. Maybe it isn’t fair to call the Legends “adequate" but, in my defense, I did say extremely adequate. The Legends were fall off the bone easy to ski which actually was part of their shortcoming. Skiers didn’t take them seriously, which is a shame because part of their best attributes was they were actually so easy to ski that most better skiers didn’t take them seriously enough. Enter the new M-Pro and M-Free. The Pros are the the titanal infused models 105mm and below and the Frees use the same Poplar core but are more off piste oriented. Dynastar is sticking to their longer gradual tip design that started back with the Chams but with a more modern take. There is much more of a Legendary feel to the new skis but I can see the need for a name change.
  • What you will miss: Just the pure ease of all of the skis​
  • What you will gain: To quote Tim Taylor, “More Power” even in the wider M/Free​
  • Insider tip: the M/Pro 84 is just a graphic change; it is the old Legend 84​

Where the Dynastar Legend was the inspiration for this article, replacement of the Monster 83 and 88 was the catalyst. The Monster’s days were numbered when Head introduced the wildly successful Kore series of skis. First to go in recent seasons were the Monster 98 and 108. This made sense as the market for a (nearly) fully cambered traditional shaped 98 and 108 was near null. I agree there, but the Monster 83 and 88 were still class leaders. In performance they were the skis to which others were compared. These were skis for skiers, good skiers. The volume of sales might have been dwindling but the quality was still there. I understand the need to streamline collections and having a two ski collection can be confusing to some ski buyers. So, let's replace two extremely purposeful skis for the sake of versatility.

For 2021 Head replaced the 80mm Head iTitan with the 84mm eTitan. Vowels aside, the eTitan is now a very wide carver and, with the 7/8ths version 85mm V-Shape V10 also in the Head line, the Monster 83 could be perceived as superfluous. I will give Head points because they will also be offering the eTitan flat, sans bindings, something that has never been offered on a Supershape ski in the past. As far as replacing the well loved Monster 88 with the Kore 87? Will the Kore 87 be a better ski for more skiers? Probably, but the Monster 88 was a great skier for select skiers. With all this said, the Kore 87 will probably outsell the Monster 88 by a significant margin.
  • What you will miss: The Monster 83 was a really good frontside ski that could play all over the mountain. The Monster 88 was the reference 88 ski with a hard snow bias.​
  • What you will gain: With the eTitan, a better hard snow ski with more purpose and the Kore 87, a ski that you can relax on and not have to think.​
  • Insider tip: You can get the eTitan flat. For Nth degree fun, consider a race plate and Freeflex FT.​

It’s a whole new world at Kästle with new ownership, a new facility for building skis and, as the subject here, an entirely new MX collection of skis. When Kästle was reintroduced as a brand in the mid 2000s the MX, or “Mountain Cross”, was the cornerstone of the brand. Through the years there have been glacier like evolutions to the series for good reason; they were arguably the best skis in almost every class they had an offering. For 2021 Kästle’s MX series is all new. While some of the widths are familiar, the skis have been completely redesigned. Gone is the need to be the best skier on the hill skier to enjoy an MX. Now it is only the desire to be better that is required. The old models were really just for the upper eschelon of skiers who could get the most out of the MX experience. Now it is a ski for the qualified masses. Kästle was willing to forgo the top 5% of performance to gain 10% more in obtainability. Common sense here is prevailing with the powers that be at Kästle. Even the best of the best skiers redlined the ski on very few occasions and by making the acceptable power-band more inviting, the new skis are much friendlier at only a slight top-end performance cost.
  • What you will miss: The top 5% of performance that you accessed 1-2% of your ski day​
  • What you will gain: More versatility.​
  • Insider tip: The finish of these skis is the best they have ever been, jewel like.​

I have been saying “Welcome to the new K2” for so long they are now on the second generation of “new” K2s. Already gone is the stellar Charger collection that has been a favorite of all of our testers and very well the most underrated collection of skis offered anywhere. Also gone are the Ikonic upper 70 to mid-80mm collection of solid frontside skis. Welcome the the age of Disruption. The all new Disruption collection replaces both of the outgoing Charger and Ikonic collections with one encompassing series that starts in the low 70mm range to 82mm. Just looking at the shape of the new skis indicates they are hell bent on being one of the more technically oriented collections offered…anywhere.

Oh, there is not one, but two women’s Disruption Alliance skis, the MTi and SC, and trust us when we say these are not your mom’s Burnin’ Luvs.
  • What you will miss: With the Chargers, you will miss a solid technical ski with race-ski like tenacity. With the Ikonics…Well the Chargers were really good and will be missed.​
  • What you will gain: A great hard snow ski that will lay trenches and expect you to be on board​
  • Insider tip: K2 sold tens of Charger skis in the US and most were from our reviews. You keep asking for narrow hard charging frontside skis and K2 is building them. You better start buying them otherwise they will stop making them!​

We can’t help but take some credit for putting Renoun and the HDT (now called VibeStop™) infused skis on the map and that all started because of the revolutionary Z90. The Z90 is a 90mm wide carver that changed people's perception of how good a ski could be. I referred to the Z90 as a once a decade ski. I was that smitten by it. When Renoun introduced the Endurance 98 V3.0 I immediately told Cyrus, owner of Renoun, “the Endurance’s shape would be good as an 88 wide ski. It could give Renoun a good one two punch with that collection.” I never meant for it to be a replacement for the Z90. In fact, I referred to it being a good compliment for it. Like many of the revolutions mentioned here, the Endurance 88 is so different in feel from the Z90 they could coexist in the same quiver. Where the Z90 stood out in this range with a unique set of skills, the Endurance 88 jumped into a sea of “me too” skis.
  • What you will miss: The hard snow feel, quick turn in and grin factor like few skis can provide.​
  • What you will gain: Off piste and mixed snow performance.​
  • Insider tip: Lets hope that we will see a limited run of Z90 Classics​


Few skis took the industry by storm like the yellow and black Rossignol Soul 7 when it arrived a few seasons ago. The Soul 7 was part of a merry band of skis that included the Sin 7, Super 7, and Squad 7 along with their women’s counterparts. These skis ended up being a victim of their own success. They were light, playful, and opened up the mountain to many, many skiers. Over the seasons the sales did dwindle and with the ski's age, even with some construction and name changes, the series got long in tooth. Over the past two seasons Rossi has been testing the waters with the “Black Ops” skis. These started off being available just for athletes, shop guys, and influencers. Rossi made just enough buzz and peaking of interest to bring the Black Ops public as their own collection. Where the Soul 7 was the focal ski of the outgoing collection, the Sender Ti and women’s Rallybird Ti are the new king and queen of the prom and definitely worthy of the accolades they have been receiving. These new skis are not anything like the outgoing models in performance, on snow feel, or even looks. While graphics can be subjective, they are the only thing anyone who has had the luck to get on the new skis questions.
  • What you will miss: The puppy dog playfulness…and the attention span to match.​
  • What you will gain: A much more planted feel on the snow and a mature feeling ski.​
  • Insider tip: A refreshing change in sizing, width is measured in centimeters not millimeters and the length in meters not centimeters. So the Sender Ti is a 1.82 m in length and 10.2 cm wide. Not that it matters, just that it is different. Oh, and the ski's sizings are scaled, so each rider gets the same experience, no matter their size.​
The one constant in ski design is change and we are seeing significant change in the models mentioned above. In some cases the changes are calculated. For others, they are throwing a design against the wall to see if the dog will hunt. Again, it is not for us to say if these changes are for the best or not but to help you as a reader to decide if these changes were indeed for you. More and more we cannot say, “I will always ski an Abcd” or "I will never ski a Wxyz”. Now is a great time to explore your options.
