Performance Combat is of course one of the top things to go after if you're using your wrestling character a true performer. I think the problem is the feats aren't applicable often unless the GM is really specifically writing the game around your character. So many people won't take them, which saddens me.
I think it depends a lot on where the campaign takes place, too. In a mostly urban one like Curse of the Crimson Throne, Council of Thieves or Hell´s Rebels, you can easily confirm with the DM that there is a crowd for many of the fights, so you could stretch the performance rules to apply as well. In a dungeon crawler or exploration-based one, though... not so much. Unless you can somehow get your combat exploits to count as bardic music - then we are talking! Sadly, I think the exemplar brawler loses a little too much for what it gets. The variant bard multiclassing may be a better idea. Check with your DM if you can get a custom perform skill approved.
