154 is what he came in against Mayweather, and Kostya Tszyu, I think thats the right weight for him. I hope he doesn't make the same mistake Oscar did in trying to be as light as possible to move quicker. IMO trying to outbox Pacquiao at this point in his career is a huge mistake for anyone except JMM and Mayweather. Hatton needs to be able to get Pacquiao on the ropes, and have the strength to suffocate his offense. At 154 he would still be light enough to move well.
