You said you don't charge especially hard. . .
The EP pros are soft. . . real soft. bombing 'fat' cliffs will result in some backslaps, as they are pretty soft, but they are still fun.
the hellbent is stiffer, but probably more able to charge. and it doesnt have the tapered tip/tail which is sikt0r. But I ride 'bents and I am pretty loyal too them.
I think you would be fine if you were convinced it was a good deal. I think you could handle them/they could handle you, especially if you arnt looking to charge too hard. They would definetaly be a fun rockered ski.
note: When I rode them they would flex so much the binders would pop me out, this might have been to the low din they were set at, but they are super flexy. powder won't be so bad though, because this only happened on groomered jumps.
