i definately think that hatton should fight at 147 because that is where the big fights and the big money is and its the place to esablish himself as a top man in the sport,
i dont even feel that hatton should have trouble at welter its just that he had to short a camp before fighting collazo and collazo is just plain awkward to fight never mind look good against, i dont doubt he can make 140 again though , although i would like to see him take care of himself between arranging bouts cos he looks a mess at the moment.
peace
