I already posted some first impressions on epic. Here is some cross post action. web page
These are the Atomic SX10m Puls TI in 170cm with Atomic Neox 412 Bindings. 105/66/96 (16m)
I have skied the SX10s now about 4 days so far this season... A couple of those have been in cruddy or slushy conditions. The SX10s do well in all the conditions I have tried them in so far. Even deep mushy slush is workable. I think Peter Kelty nails the review. The ski holds well, its predictable, versatile, and is very quick turning. It doesn't beat a person up after a full day either. The SX10 has the best hard snow / ice grip I have experienced. Much better than my old T50s and better than the current generation Volkl S5 TI...
The SX10 is a great carving ski but is not that great arcing high speed turns and laying trenches. I have definately had to compensate for the relatively narrow tip when transitioning. I have not enjoyed the ski in bumps, but I still feel it has some potential. I think it would be much better in a wide open bump field (similar to goose bumps, devils drop, the face, etc... ) than it is on the rutted, tightly confined lines currently available at 7S. The biggest gripe is the difficulty really laying trenches in long turns at higher speeds.
I have tried both the "centered" and "forward" positions on the bindings. The skis seem to be more stable and forgiving in the centered position.
Overall I have decided that though I like the ski that there are better options for me. I reall ylike to be able to rail groomers at high speeds and the SX10 strangely does not see truly adept at doing that. I just found a pair of Matron B5s which I had a chance to demo and simply loved as a carving ski. They also seem to be very stable in crud and I think will replace both my current mid fats (Bigstix 7.6) and my SX10s.
The quiver is ever shrinking but I think the quality is going up.
