Started in Kenpo, moved to Jeet Kuen Do, and then finally to Muay-Thai and Brazilian JJ with Relson Gracie. MY and BJJ were the best. I went 5-1-1 in smaller shows before giving it up. It didn't make much sense to risk 600$ in dental work to win a 1000$ prize.
Relson's BJJ started with attacks and escapes from the mount. And even the black belts from Rio drilled that and the guard more than anything.
