Rolling dismount: leg crosses over in front of you or behind? When doing a rolling dismount, one foot stays on its pedal, the other has to cross over somehow. Would you suggest crossing over in front of you (while sitting, folding you knee to allow the cross-over) or behind you (standing on your pedal and extending the other leg out behind you to cross over.

Note: I don't mean to know which you prefer, rather which is safer/easier/quicker than the other, and why.
Unless you have a Victorian ladies style frame, crossing your leg in front of you is a fine way to crash.
