ive riddin the hellbents and the JJ's. and my take is that the JJ's are a way better ski, they are light yet strong.  aggressive skiers can charge on them and they blow through crud like its nothing.  the hellbents are ok, very sketchy at speeds on hard snow.   i loved the JJ's wish i didnt have to sell them.   however good luck finding them in a 185 which is really what you want if your over 5'7 150lbs or so.
