LMAO! True, they don't work just like rubber guard. LOL.
I don't understand, either, why a lot of schools don't permit leg locks. The school I started out with as a white belt was that way and I have suffered in that part of the game ever since. When I first became Moonhead at Indy, I didn't want that to happen to my students and Eddie told me to contact Coach Herzog. I did, Coach gave me a lot of advice and we did leglocks for a straight month. EVERYONE. With an emphasis do not crank while rolling. Ever since then, several of my guys have become leg lock wizards and will hit you with a leg lock in their sleep. If other gyms don't want to do leg locks that's fine by me. Good luck trying to catch up with my guys when they finally make the rank. It'll probably be too late.
