Pathfinder society Build Advice

[Oznof]

I am working on building a Brawler / Wildchild; I noticed that I can take the mutagenic mauler as well at the cost of Martial flexibility.

I was wondering how important or useful is Martial flexibility and can mutagen stack up to it or not.

I'm playing a regular Brawler right now. So far, martial flexibility has been useful, but you have to either know your feats really well, constantly consult the text, or come up with a system of some sort to help you keep all your options straight. I'm going the latter route right now.
