The Kendos have really helped me in skiing. I've improved, to be sure, regardless of the Kendos, but they do afford a sense of confidence because they're so well damped (probably some other terms would more accurate but I think it works)
Often in variable snow which is the norm right now on the east coast, constantly hitting pockets of skied off powder, ice, water/slush and hardpack all within 30 feet of each other and randomly, makes other skis I own feel unstable and get knocked around a bit. It's more of a sensation probably than an actual problem, but enough to be very distracting and cause me to get a little psyched out...
...not the Kendos, they blast through all of it. Initially I had to work getting it on edge (and still do but have come a long way), but once I was able to, I could reap its benefits.
So even though it's technically a less approachable ski than say an intermediate ski, it boosts a real sense confidence more than all other skis I've been on, and thats enough to allow me to focus on getting to the next level. Steep Blues and Black diamonds with the aforementioned conditions aren't as daunting now.
Can't say enough good things about this ski.
