listen to me!!
I was looking for a ski just like you described, i was dead set on a soft, big rocker, flat underfoot wide ski, hellbents were at the top of my list for that, ive skiied them before and they are definitely playful.
I recently found surface one lifes for pretty cheap in 179 and decided to give them a try, even though they are stiff, have camber underfoot, they at least had big rocker, and every review i read said they were very poppy and playful. so ive had a couple days on them so far and they are awesome, ive skiied bacons, hellbents, ep pro's, opus's, jj's, and kung fujas's. and these are probably my favorite, the ep's and hellbents are close.
you can tail butter like crazy, the abrupt big rocker lets you sit on the tails and flex em just enough, you can literally butter for miles, and pop out of butters big too, like land a rail in a tail butter and pop a 180, ride up to a rail in a butter and pop big onto handrails, and press down the whole thing. which is another thing they are amazing at, they can do presses like crazy. nose butters are a little tougher, but mostly just take getting used to, you kinda have to hop into them more.
in powder and crud they are super super stable and poppy, you can pop off anything. the charge hard, then the big rocker lets you slash pivot and slide around at any speed. good for landing off big cliffs. obviously have no problem floating, and one of the best things is how you can charge into stuff at speed, and ride like a butterey slashey thing on the tails, super fun on rollers.
it does so many things it shouldnt, its stiff and super stable, but super buttery and playful, big rocker but awesome on big park jumps and carving. wide but awesome on rails and its light. not much sidecut but crazy nimble and slashy. its a 112 waist powder ski but skis park better than some park skis.
you should definitely take a look at those, coming from someone who's skiied a lot of stuff, they are highly reccomended, cant go wrong with hellbents either. just wish they were a tad skinnier tho.
