a stiffer tail perhaps? i can't really remember, but I do recall reading that there was some minor modification.
I wish I had like...any money at all right now, but I just moved home from college and am poor as balls 'till I start work again. If the 175 rockets are still around, I'd definitely be interested in a month or two. I have too many skis as it is, but too much overlap in the quiver, so if I could get rid of a pair or two I can justify picking these up as a do-all pow ski.
