Hey Thaiboxer

I've not read any of the posted replies from the guys. Anyways, my view is this:

Always push off the leg furthest away from the direction you are going. By pushing/thrusting off the leg rather than 'stepping and dragging', you are able to generate the explosive speed to get in, unload your shots, and get out again. This to me seems like cold, hard logic. Stepping and dragging is for journeymen heavyweights.

I've put some of this stuff on vid here. Hope it helps mate
