Yeah, i'm gonna ask to try it and let him try it on me, just to see what it's like and how to get it, etc.
I think another reason why nobody uses it anymore is because in the Bulldog choke, you're so close to a Rear Naked Choke, and as you said, it's not a reliable choke, so they just go into the RNC.
when you apply the bully aka headlock you are already pass the chance for rnc. he is in position to take your back, it is best to over hook thier near arm setting for an uchi, or turn into them or total disengage and reset
