So...I sent that youtube link to my instructor (Michael Bartlett) yesterday. During our rolling session last night, I'm in mid roll with someone else, trying to get to guard so I can hit this tech, and I hear my instructor call out my name. I just happened to be at a point where I could turn my head and look in his direction, just in time to see him hit 100% (from half guard) to the truck. I didn't get a chance to hit the tech myself last night, but he and I talked about it afterward, and he was really impressed at how smooth the transition was, especially having not drilled it before hitting it live. Great tech, certainly effective. Thanks again for sharing...can't wait to hit this myself.
