I'd go left. and I'm a rightie.
Reasoning:
I was always told that if you keep your left hand on a wall at all times, you can't get lost in a maze - you'd always find the exit. Plus I think it's a defense mechanism to keep your dominant hand free whenever possible just in case - maybe something to do with how I think but I like any obstacles on my left side, and in the UK turning left would mean traffic comes from behind and the road would be on the right side - so by turning left, I'd have my left hand nearest the 'wall'.
Damn I sound weird now!
