I can't tell the difference between goofy or natural in my own riding, it's almost confusing to me to hear you guys talk about it! I don't have a preference of a front foot, be it snowboarding, surfing, kiting or windsurfing.
Same thing riding toeside, either way, feels the same to me. I'm equally sh-t either side.

Skateboarding, however, I can only really do left foot forward (and poorly!). Probably because I never had to switch.
