dude, you should be on something in the mid 180s. if your 6 1, and 150, you could definatly benifit from a longer ski. im 5-9, and am on 183s, and was on 177s last season. (longer skis are soooooo much better, in every way imaginable). unless you are JUST starting off, get something longer. you wont regret it at all.
