I find that when sparring hand techniques do me a lot more favours than high kicks but a well executed side kick can smash through the opponents guard and land on target.

Sweeps are also very efective but everyone I've come in contact with seems to use ashi bari, no-one seems to use a Bruce Lee style kung fu spinning sweep which looks very effective

What kumite techniques do you find useful? Do you agree or disagree with what I've said?
