I agree with Matt on the gi issue. The gi has made me a lot more technical in my setups, escapes, counters, and especially in submission defense. As for Hedi, I've always heard that on the path to blackbelt you have to tap 1 million times. Getting submitted is a learning experience when you quit getting so frustrated with yourself. When your in the gym your not competing, your learning, so relax and go for it and if you get tapped learn from it.
