you should post in gear talk but anyways where are you skiing in pa? but it really depends, if you want a lighter ski go for the invader, much better for rails. or the anthem for stiffer and better for jumps. are you just looking for line?
word, if you're only just learning how to ski i'd probably go for something a bit stiffer than anthems or invaders. with those two you're gonna have to centre mount them which could be a bit hard for learning on, i dunno maybe it would be just as easy learning on soft centre mounted skis. either way don't expect to be able to go too fast on anthems. rossi scratches are good I forget what they're called now though / are rossis still being produced? the k2 silencer might also be a good option, slightly softer than the extreme and pretty cheap
