So deliciously light! I'm 5'9", 170 lbs. I went with the 174cm for kick-turns, herring-boning, side-stepping, boot-packing and backcountry ballet made easy. I put 45 days of backcountry on them last season in allllllll the conditions and these skis continuously delivered. Admittedly a little squirrelly at first, but maybe that was just more of a learning curve? Despite having skied all my life and having previously rocked the Reverends and the Empires, I've never skied anything quite like this! As I get older, I need all the help I can get. These super light skis married to Ion 12's increases the time and enjoyment in the mountains in the absence of fatigue. 45 days in and the only sign of wear n tear is slight chipping of the decks on the inner sides of the tips where the skis inadvertently came in contact on descents. I applied some marine resin and problem solved. I do have reservation about the fragility/longevity of the ski given that it's full carbon, but so far, so incredibly stoked with them. It's a love story. ps. the magnetic edges, yeah, it's a thing and makes trannies so quick and dirty.
