Nice tutorial. Aikido is my favorite mod and I tend to use my hips, knees and my torso joints to dop most of the moving. I also like using my pecs and shoulders to do quick counters or change the momentum of the enemy or mine. Lastly, I don't do any openers(usually) - just clapping will do the trick and I use my opponent's force to make it mine combined with my force, he can't counter back. So bottom line, I wait for the opponent to attack first....
