i agree the ski doesnt excel on groomers, but it is definately sufficient for skiing around on warm days, or after it has snowed and its not icy. but for a fat rockered ski it handles well on groomed. and just fyi the hellbent isnt soft underfoot, it has a more medium stiff flex which is what allows it to still handle decently on piste.
if you are looking for something a little more groomer oriented check out the obsetheds, less extreme rocker and narrower but still fat enough to give good float, i have a pair and they kill it everywhere. super stable, and i weigh 200 pounds (i have the 189s). they kill in the park, i did some blind 360 switch ups on mammoths sharkfin box(up drop down) and was able to do pretzels (2 on 2 off)
