This is going to be a bit weird and most probably pointless, but it's not like you've got anything better to do right?
I can't decide which my leading foot is. When I pedal wheelie, I lead with my right (which is the strongest, the one I primarily use for football and so on). However, when I manual or bunny hop (well, try to), I prefer to lead with the left for some reason, which in turn makes me lead with the left on the descents most of the time.
Is this weird? Bad habit worth getting rid of? Or just something to ignore? Can't say for sure if it affects my riding at all.
