Replying to Popular vs Unpopular

alright, so being that its getting close to the season, for me atleast, i have been looking in to buying some twin tips. now i've heard about how some of you guys like libertys and surface skis but how do they compare to some of the more well known twins like the ones that k2 and salomon twins. i havent ever seen any one at any of the resorts ive been to around me that has people skiing on the liberty and surface skis. so wats the diff?
