I'm a big fan of wrestling and catfight shows. I've had fantastic shows in New York, LA and Chicago over the years. My experience has been that professionals put on the best shows. Most providers don't have the training or experience to safely put on a good show. The majority of providers aren't familiar with the various styles, moves and holds you may request. Most of the time I've ended up getting 2 girls rolling on the floor giggling. Which is fine if that's what you want.
Haven't done a mixed session, I would think that would require a skilled lady to do, but again it depends on what you're looking for. Good luck!
