So I have the SX FIS 185 and know the ski well. At this point I have 4 days on the WRT Pro in 172. They are completely different skis. I also suspect the 162 the 180 and are pretty different than the 172 and hope at some point to get on the other lengths to compare. The SX FIS requires patient initiation to hook up, as one might expect. In the turn it’s about as stable as a ski like that can get. If you try to overpower the tips, it’s slow to break the tails but will. The Pro on the other hand, at least with the factory tune, has pretty reactive tips that will overreact if you get too far forward. It’s happier skied from the center until the end of the turn when you can recruit the tails for a quick release. I find it kind of easy to ski, if you’re fore aft balanced the way it likes. Skied that way, I find it‘s happy with short or medium radii. It doesn’t have the bobsled feel of the SX but I like that as it‘s more all mountain and snappy.
That said, I weigh 175 these days. @anders_nor, I think you’re in a greater weight class and I think that would really matter with this ski. It does on the FIS SX, I was 30 pounds heavier in the past and it’s more work to ski it these days. Whereas on the Pro I feel as though if I don’t try to overpower the ski it’s happiest and doesn’t demand a lot of effort. With GS turns it feels like a tolerant SL. As an SL it feels like an SL. Fore aft is really key here. When I’m balanced I feel like the ski can do almost anything with grace.
Is it worth the high cost? Well, not really, there are so many fine skis for less. But it’s distinctive with a very broad performance envelope so it ultimately depends on how you value that.
What you will find in the 180 is they need to be skied more forward than the 172. Centered skiing doesn‘t work so well. Tips are more difficult to access and you will have to work harder. But when you get it right the kick out of turn is so strong you get air every turn.
