kylemcleanGonna go with the 1080 but I remember it was either volkl or Solomon had a race ski back in the day that won just about every award ever for a few years in a row
I am assuming that the OP is talking about most decorated "freeskis" but since he left it open, for sure a race ski will win this question.
But there are two points to consider:
1. Skis often change names every couple of years because the ski evolves (so winning streaks aboard Atomic 9:18 were ended by the Atomic GS:11 which were ended by the Atomic Doubledeck GS, etc etc.)
2. If a ski keeps it's name for a long time, then that ski (even though it may have undergone tons of changes) will be the winner simply because it has been around the longest. For example, the Atomic Punx has been around for almost 10 years and has a lot of medals to its name but the ski has evolved (changed) over those years as well.
