I currently and have been training gi jiu jitsu my full bjj carrer(a little over a year) and someday hopefully i will train at a 10th planet school, there just isn't one close enough to me and i am happy with my gym so far. I was wondering if anyone here uses any rubber guard techniques or solely uses rubber guard with the gi on? If not why do people never do this when it seems to be pretty effective when used correctly?
