Xtremist: I don't think they would be too big. I personally would go for the 191 MadTrixx, but I have always appreciated a longer ski with a waist that was a little narrower (I ski mostly east coast but like to go out west once or twice a year - not enough to justify a serious powder/BC board). The 181 1080 should be good, since its waist is larger (80cm) the shorter length shouldn't be a problem.
Telefreeride: big boards, free heels, no poles, all soul
