- left or right leg in front is better?
- depending on situation.
if we wish to protect knife from being kicked out of hand for example, left position is better. if we face knife though, right position is far superior for we do not wish to have left arm cut. but i think that Versatility is important in many other situations as well, for example when we have a muscle strain. i've trained few combat positions, with the same arm & leg in front at the same time, but with different foot positions.
i've heard on training lesson - that with left arm in front, it's more defensive position - for left hand can capture or divert the opponent's knife - then we can follow with counter-strike. i'll have to check throughly to confirm.
