I'm an intermediate level male, 6'0'', 185lbs, stay on groomed blues 90% of the time, and ski moderate speed. I'm planning to buy some Fischer Progressor 800's after demo-ing them earlier in the season. Tried them at 165cm, which felt fine since I was coming off of 163's (my beginner skis) but since I'm getting a little better and comfortable at higher speed, was thinking of getting them in 170cm. I prefer making shorter turns and by no means am I a speed demon.
I can get a pretty good deal on the 165's but if 170's would be better, I'd shell out the extra dough. Will the 5 cm make a difference either way at my level? Obviously, like everyone else I hope to improve in ability. Thanks for the advice.
