For Extreme Catfights would have to add Bae Fight at clips4sale, Alexa Brooke Vs Paris is one of the best all out Catfights I've seen... Hard body punching, face slapping, tit and pussy attacks, this fight has it all. Sexy Black Vs Blonde showdown with trash talking.
Suite Fight also has good Catfights.
Antscha Prod doesn't have the best Catfights, but does have world class Wrestling and Grappling with Fetish, Catfight and Boxing matches at her clips4sale site.
As for the FD Vs FoxyCombat debate... Would say both get high markers for the number of sexy fighters they have filmed over the years. Both have amazing matches and also a few not so good matches and need to find fighters that shoot your style of match. Some of the girls want to win more then others. Would have to give Fighting-dolls the edge for their live event matches as the girls seem to show up to the events wanting to win in front of the crowd and the matches have a extra edge that I like.
