These skis are great on harder snow or miserable off piste (breakable crust, windslab, refrozen crud, etc.) conditions, but they favor a bolder approach. They also ski on-piste pretty well considering their typical widths. They don’t ski backwards all that well (usually).
The skis have rocker profiles that usually fall into the s-shaped camber category, with elongated shovels and shortened/flattened tail rockers. Tip and tail geometry will be less tapered than that typically found in twin types. The offset for binding mounts is generally more centered than twins.
You can familiarize yourself with rocker types here.
