Im gonna throw in my two cents in this one, if i haven't already. Rocker skis are a wonderful concept, but its mostly a great concept for the BC then for the park. Pep still rides his promodel 90% of the time in the park, Eric still rides the Lizzies in the park, and i think andy is the only one who rocks the hellbents 100% all the time. The fact is the only thing the rocker will be better for park is butters and presses.
They would be HORRIBLE in the pipe since the edges will not really bite at all, and the rockered shape will take all the pop in the ski. Carving off any sort of jump will be 100 times harder, and the pop will just not bet there. In an urban setting they would be decent, but again you need TONS of pop when you ride urban. Rocker skis will make presses and nose slides way easyer, but you can still do them fairly easily on regular skis ( look a tanner rainville......that guy does not need rockered skis to OUTBUTTER anybody out there). It's a great concept, but i think park revolutions will more come from fully symetric skis, with different widths, flex patterns, sizes, cores, base designs, and edge design.
I can't wait to have a ski with copper or aluminum edges to slide rails with. Softer metals are the way to go for sure. Wider skis in the park seem like a great idea too. While the rockered skis will devellop a different style in the park, they just will not perform nearly as well as a standard park ski.
