Good list, I think Hatton vs. Castillo at 140 should be on the list (pending Castillo makes weight, which right now it looks like he may have a problem with). Taylor vs. Wright 2 should happen as well as Hatton vs. Collazo 2, but they prolly won't. Personally I'd like to see Darchinyan vs. Wonjongkam as well.
Any alphabet holders at HW fighting each other would be nice. Tarver vs. Clinton Woods could be entertaining as well.
