Stuck on picking my 7th level fighter feat

[The Great Miguel]

We're playing Curse of the Crimson Throne, and we just made level 7. This is the only level I'm not sure of what feat to take as starting next level I begin to qualify for more feats that I want than I can take :)

Here's the build:

Human Fighter 7
Str 21
Dex 18
Con 15
Int 13
Wis 15
Chr 15 (we roll stats, and I rolled amazingly well :)

Feats:
Weapon Focus(Falchion)
Weapon Specialization(Falchion)
Power Attack
Dodge
Mobility
Spring Attack
Combat Expertise
Whirlwind Attack

Traits(bonuses as I forget what they're called):
+1 will, +1 K(religion) and class skill

So top contenders are Lunge*, Iron Will, Leadership and Blind-Fight.

We are using core only with case by case use of APG, though those are rare.

Due to the fact the they named the feat "lunge" my DM ruled it won't work the way implied by the feat for WW. Instead I pick a primary target and I attack the area around him out to a max of 10' but not the squares opposite side of me.

For Leadership I'm wanting to take a Pixie cohort as I am a Priest Desna, and my Pixie would be a boon from her to aid me in my priestly duties. Once I reach high enough level that is. The Pixie will then take cleric levels to compensate for my lack of spells.

I'm open to other suggestions.

With Spring Attack and Power Attack, I would tend to recommend Furious Focus.

Vital Strike might have good synergy, also, if you only make a single attack in many rounds, anyhow.

Lunge ... with your Whirlwind its a no brainer.

+1. It's good even for other attacks. :)

EDIT: Re-reading your GM's proscription on the feat (which makes no sense to me, but whatevs), see if you can get furious focus.
