I’ve only been out on my Rockers for about 5 days; due to the late start here in Tahoe. In heavy, thick snow I was actually having problems with tip dive. I’m not that big, 6’ and 200lbs. Bindings are STH16’s.
Comparing the Rockers to my pair of “woody” Sanouks, the boot center of the Sanouks was 80 cm chord length from the tail, and the Rockers was 83.5 cm. Lengths are almost identical at 193 vs. 192, the Volkls actually have a taller tip due to the extended nose scoop. Aside from the width differences, the skis are somewhat similar, close to flat under foot back to the tail with a slight rocker up front. The Salomon’s being built that way and the Sanouks developing a slight rocker with use.
Anyway, I moved the bindings back 2 cm and got to try them out on Big Wednesday, 3/4 at Mt. Rose. The change was subtle, they still felt the same in mixed powder and crud and definitely did not tip dive when the chutes finally opened. One run of crotch deep virgin powder and several runs of knee to waist deep powder, chop, and slide proved them to be more stable in the heavy stuff. That being said, I still skied my Sanouks for the first hour, until everything was tracked out and then switched to the Rockers. Yes, they are heavy, as in "where's the lead?" heavy.
I still haven't figured the Rockers out. I don't know if they would have been any better than my gold 190 Gotamas as I didn't ski them back to back. The Sanouks are utterly sublime in fresh untracked, but cannot handle Tahoe chop and crud.
As they say, your experiences will probably be different.
