Yeah I don't know how much either strap will help with "surf stance" if that is what you are shooting for. Ever boarded with both feet pointed forward? Think it through so you don't have to redo your mount points in the Summer...
This is how I ride too, well my other foot is forward. Maybe my front one is turned a little, but I was going to steal slut's idea and put a few nuts in there so I can adjust if need be... But when I snowboard, my other foot is forward, and face to the side not downhill, like a compleat 90 degree.... Thats why sluts idea, to me, seems like the best of all worlds, just move it around a bit if it doesn't feel good..
Everyone always tells you, ride how it feels best, don't they?
