I just watched the first vid and enjoyed it quite a bit (though I probably missed a couple things because youtube doesn't like my laptop, and I was keeping the sound down so as not to disturb others who are trying to get to sleep). It sounds quite similar to some stuff my BJJ coach was describing when telling me about a "practical self defense" course he's going to offer in the near future. Working from natural flinch response, closest weapon to closest target, etc.
Maybe I'll have some more to say later, but I should be getting to bed now!
Thanks for posting the vids.
