For me I ski with my right foot in front, I am right handed, I kick a ball with my right foot, Any board sports I go left foot forward (wakeboard, surf, skateboard, snowboard)
Hockey I shoot right, I golf right and I bat right. I also play with my right hand for racquet sports.
The other one that is interesting is when biking (hitting jumps, riding DH or just coasting) I feel more comfortable with my left foot forward and my right foot back.
