i'm a fairly advanced all mountain skier but just getting into park so i figured now would be a good time to upgrade my skis to a nice pair of twin tips. i want something thats good all mountain and kinda have my selection down to 4FRNT STLs or MRs. i was wondering, which skis do you think would be most appropriate for me? are the bluehouses worth the extra $$? what are the pros and cons of both?
