Funny. At the last TD I had a good talk with Vin who trains at a Straight Blast Gym, and this other guy who had Aikido experience. We were discussing wristlocks and where they come into use. We all agreed that they were damned near useless in a fistfight, but as a tool to stop a fight in the escalation stage of the pre-fight in an SD scenario they were perfect. Just thought I'd throw that out there. And I still have no qualms throwing down with Tom's guys. I don't know what their credentials are on the ground, but I'm not really afraid of going there with anybody regardless.
