Looks like your doing some homework.
Tracy, I know there is a tape series out called "the lost art of hooking."
You might want to check it out, look in "Blackbelt Magazine" for the advertisement. Check online at Panther Videos.
I agree with what I read pertaining to fighting from the back. As I frequently remind my students, the guard (on one's back with the legs controlling the opponent) is not a primary position, but a transitory position used, only when needed, to sweep to a more dominant position or hunt for a quick submission.
See you on Saturday!
