Very easy to switch them, they take same mounting. The shapes are quite different. Yeti gives more float, better carve, and superior groomer and packed snow performance, at the expense of some HP in deep snow, and terrible crusty behavior. The Traverse ski is the best all-mountain ski. It’s a compromise in some degree, but it just works on everything.
I believe that the yeti works so well in pow because it has a “waist” that keeps snow under it. However, this waist also compresses snow on sides and robs HP in the process. I have not tried the cmx ski but it looks to me that they stole the yeti design but eliminated or reduced the waist.
when I had yeti ski there were days where the crust made the bike almost unridable, like it had a mind of its own, while the TS guys couldn’t even tell there was a crust. But when the yeti ski is happy, it’s the best I’ve tried. If racing on a circuit, no question it’s the best. We get crust a lot though, so for me the traverse ski is best. It’s also the cheapest.
