This is one of the best things I like about Lockflow. There is this grip that I have been working on and when I woke up this morning to do my morning Lockflow.com ritual, I found another slick option from this same grip by Dr. Sick. Oddly enough, I call this grip the 'Rev' grip, a shortened name for word reverse.
Dr. Sick does a great job of breaking down this reversal and also plugs a two day workshop, If your able to go, you should, as Brian also puts out class material.
