I still work rubber guard (much to the chagrin of my sunday instructor, who regards it as shennanigans. Shennanigans, i tell you)
Although, to be honest, i'm teaching rubber guard to myself, from books/videos, with the help of a partner. I know its not ideal, but point me to the nearest 10th planet school in detroit, then we can talk, lol.
Right now, i use mission control/new york. Mainly for control, and setting up some sweeps. I don't feel very secure in chill dog yet, but, i have pulled off the omaplata from the guard pass (once in chill dog, lol)
Mainly, though, like i said, i use rubber guard as a unique way of controlling my opponent...i hope to add in the sub game, but its hard, when learning from a book, lol.
