To start, I'm 6', 200 lbs advanced intermediate skier. Today I tried a pair of Cham 97 in about 4'' of new snow. Just for the sake of comparison, I have also tried a pair of RTM 84, a pair of Outland 87 and a pair of Enduro XT 850 under approximately the same condition. I found that the Cham 97 does not float much better than a pair of 85 mm waist. They both sink to the bottom when standing still, and when I pick up the pace, all of them float ok, and turn without much problems or difference in powder. Maybe the Cham floats sooner (or at a lower speed) than those 85 mm, but not too obvious to notice. Maybe either I'm too fat or my skill is too rough to sense that, or both? However, I do notice the Cham requires more effort to turn, and much slower edge to edge especially on harder surfaces than those of 85 mm. So sorry about all the babbling, but I am just curious why many people chose a pair of skis of around 95 mm underfoot over a pair of 85 mm as all mountain. Is it because of flotation or long-radius style preference? Or am I just too heavy to sense the flotation difference? (I can see a pair of 70 ish carving ski does flow much worse and be less versatile)
Should I look at 105 - 115 mm for all-mountain, mainly for powder and back country use (maybe do some AT)? Just ordered a pair of Vwerks RTM 84 for all mountain, front side biased use. Thinking of building a 2 ski quiver.
