I have only used it from the back. From the back I love it. I will try and lock it in tonight in open mat before class. The only limitation I could see would be if the person is too big to get the triangle locked in.
I watched the Fujii fight and I love how Kyra worked from the body triangle up to the high guard. I have been playing with that (high guard) a ton. If I can get a high guard where one leg is basically over their shoulder I have really been able to attack quickly.
What we think, or what we know, or what we believe, is in the end, of little consequence. The only thing of consequence is what we do. -John Ruskin
