Next year my friends and I are planning to make a big trip out west to ski some real mountains. So I am looking to pick up a pair of powder skis over the summer, I am currently looking at getting a pair of fatypus i rock's since there is a crazy deal on them right now. M problem is is that I have never bought a pair of powder skis before and don't know if I should go with the 186 cm or the 176 cm. If it helps I currently ride a pair of 178 cm j skis, I am 6' 2'' and 200 lbs.
Also I normally mount all of my skis on center since I ride a lot of park. Would it be better to mount them center or 2 cm back of center?
If anyone has any experience riding the i rock's I would appreciate some info on them since I haven't been able to find many recent reviews of them.
