I just picked up the 157 and spent the last week and a half on it through the I-70 corridor in Colorado and it was sick! It rocked every set of conditions the mountains threw at me. It rips through groomers and hardpack, you can really lay down an edge and let it do it's thing. The magna traction worked great in some of the icier conditions that I ran into earlier in the week, it's got great pop coming off of rollers, cliffs, etc, and best of all it floated with ease through a foot or so of powder. Absolutely love it!
