If you're going to get good at grappling, I'd recommend you do that earlier. Power Attack is going to hurt a lot at early levels, especially with your -2 from flurrying, so it might be worth pushing that back. I'd recommend picking a style and sticking to it- either grapple, and do it well, or punch, and do that well. It's hard to afford both the Weapon Focus chain, Pummeling Style chain, and the Grapple chain.

Overall, I'd recommend staying away from Winding Path Renegade. Unless you're really attached to the School Focus and Monk Moves abilities, you'd probably be better served by the extra 5 AC over 20 levels and 3 combat feats that the base brawler gives.

[Shaffi]

Yeah especially missing 3 combat feats hurts a lot. But the unblinking flame adds a lot of flavor.

So should I chose one of 3 chains or two of them ?

[My Self]

I'd pick just two of them.

I'd recommend taking pummeling charge asap. You'll be charging alot more than you'll be full attacking. Combine this with feather step slippers and you'll almost have a guaranteed full attack every encounter.
