Nice. I broke someones foot in a Submission match doing that toe hold once, except I was on my stomach, on his leg while he had my feet trying to apply a hold. I got the figure four in and just applied pressure, myself knowing that it was basically over and he had to tap. I just kept appling pressure until he tapped, but he never tapped, and after about 7 seconds I heard the crunch of his bones and his foot just look contored and out of place.
I think I know what youre talking about, because when I apply a toe hold, I do a forward roll (or a somersault....I think forward roll sound s alot cooler) while holding on to the sub so he cant escape it. Also try taping someone in mid roll. Very very cool sub to show your friends.
