Tim - don't get me wrong.
You get out there you want to do well - it feels good, it's fun. However in the process you learn to control your own adrenalin, your own fear and find out what works and what doesn't.
Randori (even full resistance) against a dojo mate is not the same - in competion it in some ways is facing the unknown. Trust me on this facing a guy you don't know that outweighs you be a hundred pounds takes balls.
Sam - email me privately - getting accomodation in Osaka is tough I may be able to hook you up with someone. I am bringing my wife and daughter so I am out of the loop. Also if you have any questions.
You mentioned tanto randori mpegs. Do you have a link for them. If you want we can ask Jun to put them up on his site or I could put them on mine.
