I've skiied the rocker 2 - honestly thought it was weak. Salomon is stuck in the past and just now trying to figure out how to make a pow ski. the Rocker 1 was a joke. The Opus and Bentchetler are both sick skis. Both have rocker for float switch and forward, both have camber underfoot for tracked out snow and groomers. Both are sick. The Bents have a little more rocker, i'd say I like them more for straight pow and I also personally enjoy a little fatter waist. The Opus are a hair softer and a hair skinnier with a hair less rocker. Probably better if you want to take a few laps through the park on this ski as well, and easier to get edge to edge on same hardpack. Depends on your specific situation- can't go wrong with either the Opus or the Bents.
