I had posted this to the bodybuilding forums but didn't get the answers I had wanted from the questions I had asked. Here is what happened: The thing with BJJ is that while it's really effective, there is a certain marketing with it that size can easily be trumped. So I'm curious on two things: Does being a male make that much of a difference or is just size ? (ie: would a smaller male do better than a female) Have you had similar experience of defeating a smaller yet more experienced female? Thanks.
