Familiarity: I've used it once or twice and have initial impressions
I had the chance to take this ski for a few runs at Stevens Pass in March 2012 when we had perhaps a foot or so of new snow. I normally ski the Dynastar LP Rider Length 186 (no tip rise/rocker) and 97mm underfoot (29 m radius).
The Cham 127s definitely gave me the float I need to stay on top and tear down the mountain. This ski had that familiar Big-Mountain ripping Dynastar sensation -- in no time I was tearing down steep terrain at high speed and these skis can take it. Also in Dynastar fashion, YOU, the skier, have to be ready for this ski. However, the new design allows a bit more forgiveness than the previous skis without tip rise but these Chams seem like they can still handle the high end too.
While the 127 mm is a lot to handle, I don't think that overall this ski was any harder to handle than my old-school LPs. It has great flotation and it is a ski for those who still want to actually ski as opposed to kind of floating down the mountain like a full-rockered K2 Pontoon.
Skilled skiers will find a Big Mountain slayer that can handle forces that come with the territory. They?re probably a bit girthy for an everyday ski but when the snow is deep you will be moving fast and smiling big.
