147 its a good fight but I think Brown gets hit too much, but he'd definitely put Tito on his ass once or twice even in a losing cause... ultimately I think Trinidad would have a lot of success with his hook against Simon and he'd hurt him too, ultimately winning the decision Simon was shot at 154 (which makes Terry Norris's defeat to him all the more embarassing) and Trinidad essentially annihlates him
I like Tito by late KO at 147, recovering from his customary 2nd round flash knockdown to dominate the fight and stop him in 10 or so rounds. At 154, I can envision a one-way rout not unlike Hopkins-Brown. If both fights actually occurred, Brown has his moments but wins no more than three rounds between the two fights.
I think Trinidad definitely wins at 154 but I think Simon's gas tank and recuperative powers at 147 make it a war. It would be interesting to see how Trinidad copes with a guy who rips the body and has a big hook of his own. I think Tito wins but I see both guys hitting the deck and big time fireworks at the end. Tito by a close decision or late stoppage.
