A little change to the rolling bow and arrow can see your submission percentage go right up!

Oooh, that's really nice.

Nice change of attack for the choke hand and roll. Judo does the clock choke also by grabbing the opposite gi pant at the knee and blocking the hip with the elbow. Very similar to the video below. I see this version at the highest levels of judo. Usually the opponent is stunned from a throw and the followup is so quick. Like you said the rules play an important part in the methods of attack for BJJ/Judo. Plus the pin factor in judo prevents the opponent from going on their back.
