I am RH & kick R foot, LFF on any board, skate, wake, snow, & can ride switch quite well. When I started trying to run the slalom course (LFF), I was constantly told to get more weight on my front foot. So one day I thought maybe I'll try just putting the foot with more weight to the front.
Better results straight up !
After a few years I tried swapping my grip & that felt better too, so now I'm RFF and Right palm up.
