If I was going to grapple, at this point, it'd be with someone my own size. And no offense but a 135lbs man is significantly stronger than a 135lbs woman, it's not even close. They carry weight / muscle mass in different places and naturally I've found men to be more aggressive, harder to break and generally have better understandings of leverage and timing.
Yes I've been rag dolled by people smaller, but, at the end of the day we were abiding by certain regulative factors that if removed would give me a significant advantage in many ways. Whilst I think many people smaller than me could beat me in sports, if you put us in a dark alley I wouldn't be the victim.
