So I have been in the market for a new ski, and I have heard nothing but praise going to the Jeronimos. I and currently skiing some 158 (short I know) Atomic Urban Punx, and I want to try something longer and stiffer. I was just curious about the length and rocker on them. I know the J-mos have rocker, but how much? If it has a decent amount, should I go with the 171 or 181? I weigh 140 pounds, and I am 5'9". I want a ski that is about to the top of my head, but since the rocker, I am looking at running length, not ski length. So can anyone tell me how long is the running length on the J-mos? Thanks!
