I have owned his "Street Sambo" series for several years and it has
become one of my favorites, due to the fact it talks about using your
grappling techniques and principles to defend yourself against multiple
opponants and various weapons attacks.
I had the opportunity to train with him at a west coast seminar this
last weekend (Water and Steel) and covered some very different and
unorthodox self defense situations.
Anyway I thought I would chime in, being that there are more
threads than usual discussing self defense. If you are interested in
learning to modify and apply your hard earned grappling skills in more
of a street wise manner I highly recomend checking out his work.
And if you ever get the chance to train with him ask him to show
you how to escape multiple attackers from a seated position (like at a
bar)! -------OUCH!

Though the "Water and Steel" camp was not an MMA camp I will give
you my impressions if you want.
