We had a student that was death with the prison guard. His PG was very high level. Made it work on everyone including me and barncat. I have a fairly developed whizzer/whizzer game, and it was the kryptonite to me. Problem was he hadn't develop his finishes, but that's another convo entirely. We do got some comp footage of him destroying folks with it, but I don't have access to it at the moment. It's such a great weapon and devastating at high levels when combined with Rubber Guard. Essentially he can't give you an overhook OR an underhook, ever, or you RG or PG him (not exactly that simple but you get the idea). I would like to develop my prison guard more, personally. It's such a versatile tool to have in the box.
