Dan - to keep this up to date will be equivalent to the labours of Hercules - good luck with it.
I know some fans will want the two WBC Franchise champions at 135 (Lopez) and 160 (Canelo) included but for me the number of belts/titles are getting ridiculous and anything that reduces them and simplifies the situation is very welcome.
