I've been a FoxyCombat fan since they started in 2007. To me, their products offer some of the best production values available today. Their image library alone (over 100,000 high-resolution pictures) is well worth the price of a membership, which also gets you access to all the sample clips. The downloads are speedy and reliable, and the technical support (3 times in almost 8 years for minor issues) is first-rate.
The Flashback series is one of my FC favorites, and I can highly recommend every match. And yes, the aerobics teacher does indeed get to mix it up with a couple of her students (11_049 and 11_054).
Another recent series I found most enjoyable is "The Challenge" series. Here, the girls are dressed in American flag bikinis with their fists wrapped. The fights take place in a small ring on a mat, consisting of some very vigorous wrestling with plenty of hair-pulling and slapping thrown in. The bikinis and hand wraps don't last the entire match (no total nudity, though), and the girls really look like they've been in a fight by the end.
