When there is a vacant title fight I think it should be for 1 belt only and unified later by the belt holders. To have a vacant title fight for both belts devalues the prestige.
TBF Colin, Dean Powell has managed to do that on his own, what devalues the belts is having unworthy contenders fighting for them.
How come nearly every Commonwealth title fight is for a vacant title, does anybody ever defend these titles? Almost as bad as 'Masters Titles'
