Just found a very good deal on the Salomon Enduro XT 850 and I am tempted. Have been skiing Salomon XW Tornado Powerline TI in 173 for three seasons and that is a good length for that particular model. I was thinking 177 because of the early rise in the XT 850? 193lbs / 5ft8ish / 70-30 on-off piste. What's your experience with the 850?
