I'm sick of these Hellbent/EP Pro/Other super fat rockered ski "what should my parents buy me?" threads.. but here goes.
If you cant demo them, than just pick one based on how heavy you are..
if you are over about 180, the EP pros are reall going to be a little too soft.. at least from what I have heard from people demo'n them this season.
the Hellbents are more practical because they have several sizes.. the 179 size is pretty much perfect run of the mill for the average person on this site... pending they arent a fat noob who shouldnt even get on a pair of these...
All the Hell bents I've seen have been mounted with Marker Jesters. Now I'[ve never ridden the hell bent to any mentaionable extent so I couldn't tell you if thats the right binding. But I do ride the Jesters on my Chronics and I love them.
I've heard people say good things about both the Deadbolts and the Rossis.
