I've seen all those fights, and everyone one of them were exciting. Particularly for me the Barerra vs Morales. I would add 2 more fights to the list Paquiao vs Marquez I, and any of the 3 Ward vs Gotti fights.
Although Hatton vs tzyu was more of a shock for me, than actual excitement.
Having not seen the fight yet, I'm looking forward to seeing it now.
