Scoke, I am 6'1" 185lb, ski at 36, but heavily trying to be convinced to ski 34. I skied on a 66" 166 amp 36 mph RFF model. I am LFF, couldn't be picky, free demo. I skied it at 34 and 36, one of the things that I liked was the fact that it carried speed very well trough the turn, no stalling at the finish. When I skied it at 34 this was a huge difference compared to every other ski I tried this year, which was too many according to my wife. Without great detail of any sort, I REALLY liked the ski. My new WR just arrived down south, so in two weeks I will get to ride it again. Before I ordered it I emailed Dave Goode and he suggested the 66" 146 amp model for me, besides the fact of weight/height I also inquired about skiing in colder water all the time, the warmest our lakes gets is mid 70's and that doesn't last long, so temp in my mind is a factor also. I got a few different ponits of view, one "big dawg" skier told me to be on a 64, another pro said 66, buddies always have lots of opinions, but who better to listen too than the man himself, I'll find out in a couple weeks!
