Im currently 5'7 and weigh 180. If I were to get in shape I think with my short stature and frame I'd probably be in the Jr. Welterweight division.
In my prime JWW, boiled down to a super feather. Was not very good really, not a natural. Used to spar a bit but never had a fight, to busy chasing girls and partying. Have you sparred anyone famous Vato?
