Rubber guard is one of those positions that you have to learn about, not really for you to do, but alot of people are playing that guard and its good to know how to get out of it... not to mention its good to try to learn. Every position is not 100%, but each offers alot to do.. the more you know, the more your grappling game can become better.
i've been playing with the "tornado guard" since i want to a Ryan hall seminar.
Xguard and Cross guard i've started to get into my game as well.
i dont think i'll ever compete hardcore, but I just love messing around.
