currently there are quite a few world catch wrestling titles/promotions around the world, which is your favorite and who's your favorite champ/wrestler?
SaxonWolf, thanks for sharing. I support Mount Evans Rules of Pro Wrestling (I call it Modern Catch-as-catch-can) - 2 falls, 2 subs or a knock-out to decide the winner. I also think that such championship should be open to representatives of all wrestling styles including submissions styles as well as Olympic wrestling disciplines. Whomever's the best will win, the Mount Evans Rules allow the best overall to become the champion.
Abu Dhabi Combat Club (ADCC) championships were always very highly regarded
