more people spin left naturally.
This, over time, has created a a common misconception that all people spin left and/or that rightside is invariably harder. Of course it totally depends on the skier.
Doesn't really seem to have much to do with what hand you are, just other wired shit, just like dominant leg and all that.
I started out thinking I was a right side spinner, but this was like 10+ years ago. After a serious head slam as a kid, I started to think maybe that wasn't the case, and indeed, left is natural for me.
A lot of people who spin left find it easier to look over their shoulder/spin rightside when skiing switch. Looking over my right shoulder was far more natural, which was problematic because spinning right was not. Maybe it has something to do with dominant leg or something? I have no clue, but it is strange.
