for me, it has mostly to do with my trucks. my back truck is tighter than my front truck, so im pretty picky about which way my board is facing. i pop off the tail for regular and fakie, and the nose for nollie and switch. when i do a trick where the board spins 180 under me (hardflip, bs bigspin...) i pop off the nose so the board ends up under my feet the "right way", especially down gaps and stuff. it's probably all mental, but i feel like i'm more "stable" and have better board control with that tighter truck under my right foot and the slightly looser truck under my left foot, no matter what direction i'm rolling.
