LINE. always my favorite company, and ive always felt they pushed skiing in the right direction. while they had some hard times and have had some CRAPPY skis throu the past few years, they are an awesome company. Levinthal is the man, and next years skis are lookin epic.
as far as quality skis, id say (no order):
Dynastar
K2
Salomon
4frnt
fischer
but as far as taking the sport in the right direction, line is by far the most active and important. i defiantly see them as a burton of the ski world, but not the burton of today, thats just a massive, sell out coorperation. maybe the burton of 15 years ago.
