Interesting thread.
Here's my history...
I ski LFF.
I prefer to bat left.
I play golf right, but putt left. (I probably should be a left handed golfer, but learned as a kid to play right handed golf) [1]
I play hockey left handed.
I prefer to ice skate and cut to the left more comfortably than to the right.
I skate board with my right foot on the board, and my left leg pushes. (RFF on a skate board)
I'm left eyed.
I'm right handed.
I prefer to ski LFF with left palm up. (I know, so weird)
I do a running long jump and plant my left foot to leap from.
I prefer to kick a soccer ball with my right. (I suck at kicking with my left)
I trick LFF.
I hate wakeboarding.
When barefooting, I feel more comfortable letting go with my left hand, holding the handle with my right hand.
[1] I want to elaborate on the golf swing.
I grew up with my Dad teaching me golf. We always had right handed clubs of course.
So after many years, I feel comfortable hitting a golf ball right handed.
But, I feel if I grew up hitting golf balls as a kid left handed, I would it hit 30 yards further.
At the end of the day, let the skier pick.
I don't care that the current top skiers in the world are RFF, advantage or disadvantage doesn't matter... they are comfortable being RFF.
