IMO he has only two options open to him and that's Forrest or Wright at 154lb, Forrest at least has a title to fight for. He won't make 147lb again and there is no doubt that the winners of Cotto V Mosley and Hatton V Mayweather will meet next year.
A Tito rematch won't happen, DLH won't fight again at 160lb either. DLH is over as a major player now anyway.
