Hai OP guy! You should check out my "what trick to do?" thread! You seem like a reals smart guy! Gotta make sure and ask some people before you just go out and try a grab! That would be CrAzY!
Personally, I like the this one grab that I think is called the huntony (correct me if I'm wrong) But I bring my left boot up to my right knee and hold it with my right hand then kick my right foot back.
