I saw an instructional on a foot trip recently. It worked in gi and no gi and the guy instructing it included 5 or 6 demonstrations of him doing it live in competition. It was pretty cool. I was skeptical of it's efficiency but started playing with it. It turned out to be amazing for me and really fit into my game and style. I want to find the video so that I can watch it again. Basically in the video the guy explained that you wanted to match your front leg to theirs, reach and grab the top of their head, pull it towards you and then trip that front foot. I've seen this takedown plenty of times, but never really set up like this (grabbing the top of the head). Anyway, if you know what video I'm talking about could you link it please, thank you in advance!
