Hi, I've been reading around and have seen many people put up ratios that can help you find a ski that will be optimal in powder for your weight, for Example: 200lbs guy * multiplied by 100mm / divided by 140lbs = 142mm. According to this factor I've found, the optimal ski width for a 200lb guy in powder would be 142, given that the optimal width is 100mm per 140lbs for powder conditions. So does a formula like this hold true? Is there is another formula that works better? Feel free to leave your opinions and thoughts.
To sum things up I'm basically trying to find a solution to get the right width for powder conditions for someones weight, not over killing it and having some 140lb guy on 130mm waisted ski's because they think it's needed to float in the deep stuff.
Thanks in advance (:
