It has a bit more than the Motive 95 or Monster 88. But it's a lot less than many "modern" skis. I think it looks like more on their website than it really is. I think you are in the Tahoe area? If you can swing by True North when
@Philpug is around I am sure he'd let you check them out, or even ski them . . .
As for what it does, the CW is that tail rocker makes it easier to release the tails in 3D snow and a flat tails gives you more support in finishing a turn. I'm far from an expert, but I believe I've experienced both of these things.
As for sizing, the 180 is a lot of ski. I'm 200lbs. I know
@Jed Peters is a big guy too, and probably a more aggressive skier than me, so he may have more to say. One of the nice things about this HDT stuff (assuming its the HDT) is the harder you push the ski, the stronger it pushes back. Again, it sounds gimmicky, but I know I am not the only one who can actually feel this.
