Do you guys think this is a good choke for someone with short arms? I can apply this choke sometimes but other times my biceps and forearms burn from trying to squeeze someone into submission with it. I'm finding it a tough choke to get tight, especially if someone has some girth? Is there anything I might be doing wrong? I try to push the back of my opponents head with my tricep right before I lock it up... I really like the constant availability of this choke though, any tips?
