I have attended Vasiliev's seminars and have seen many of the tapes
seeign as nobody is really focusing on Vasiliev..let me tell you that what they do is incredible stuff. Furthermore, I have also heard that what they show at seminars and on videos is only a portion of the principles and theories that they reserve for themselves.
They hit like mules and are taught to be as pliable as rubber. That about does it..like anything there will be things u like and don't like..its a damn good system though.
