There's catzreview.com, a uk company that you will find links to in the producer announcements section of this forum. My favourite from them is Elle Black vs Flawless, it's short but very sweet! Real needle between two gorgeous blondes with a very emphatic winner.
Fightingstyle staged some great catfights at their earlier meetings. They havn't updated for a while now but I presume the site is still alive. I would recommend the night-time catfight between Lia lebowe and Artemis. Some of the falls in this fight are the sexiest and most intense you will ever see in an unscripted match.
Everybody's tastes are different, but two other fights that really stand out for me are Irish vs Johanna and Irish vs Regina 2 by East Coast Cats.
I have to say that, considering neither of these matches is topless, they are rather expensive at $27 dollars, but to me at least, they are worth the money.
Irish vs Regina 2 is a rematch of an earlier battle that was decided by a single submission scored, literally, in the final seconds of the fight. This left "issues" between these two very competitive young women and wow, do they sort them out in the rematch!
Like in the first fight, there is nothing to separate them for maybe 15 minutes of slapping, hair yanking and constant bitchy trash-talk till one begins to tire and the other just grinds her, physically and verbally, into the mat. The girl on the receiving end of what must have been a very humiliating experience never stops trying to turn things around - or talking back - but her final words are a despairing "Oh ... I GIVE!"
Lol. That's catfighting for you!
