Need advice on tank build

[Nasty Canasta]

I'm about to get to 13th level and want to add a single level of an alternate class in order to aquire an extra feat to help my build. I'm looking for any "tankish" class that provides me a bonus combat feat, I require either Combat Reflex's or Combat Experience.

My Alignment is Chaotic Good, and I meet all requirements for either feat alreadyif that's important. I also have Barbarian levels so I can't change my alignment to take a single level of Monk. Unless there is a Monk Alt class that allows a non-Lawful alignment.

The obvious choice is 1st lvl Fighter(bonus feat), but I'd prefer any alternatives especially if I can find something that might help my Will saves.

In case you know of a Prestige class, here are a couple of my base info for any preReqs.
Base Attack +10
HD 12 (6Barb/6Inquisitor)
Fort 10
Dex 4
Will 7
Feats: Dodge/Mobility/Power Attack/Outflank/Exotic Weapon Proficiency Falcata/Furious Focus/Paired Opportunist

Thanks for your time!

You could just ask your dm to allow a non lawful monk, or a non chaotic barbarian. Alternatively you could take 2 levels of fighter for the high guardian archetype it let gets you combat reflexes and lets you use str instead of dex for the aoo allotment if you are an str build.

Kinetic knight
Gives you con instead of int when qualifying for combat feats and gives you combat expertise
Does cost you a bab though but you can always have a weapon with you
