It appears that once again at the camp this year there will be some good grappling instruction. Wes Tasker will be there, Jack Summers will be there, Mike Murphy will be there, Raffi Derderian will be there and probably a few others.
If you have any doubts about the validity of grabbing a wrist or a hand and twisting it until they writhe with pain, seek these people out, spend an hour and hear what they have to say and look at what they do. You will be pleasantly suprised! If you don't know jujitsu from a Juji-fruit then now is the time to learn. If you already do these things, take a look at what other people, of different styles and curriculums do. I, for one, am looking forward to it!
