Alternate feat for Empty Hand MA Style

[Crothian]

Okay, in OA they have the Martial art style, of which one is called Free Hand. One if the feats needed is Eagle Claw Attack, a feat that is basically worthless. So, I'd like to replace that with a useful feat.

I was thinking of Improved Sunder (S&F) or maybe Hammer Blow (QM). Any ideas or suggests?

My first instinct is to tell you to be a man and suck it up - Smashing some punk fighters Greatsword with an open-handed blow is pretty spiffy. But I have the feeling you offer that ability to monks in your campaign without a feat, which I have no objection to.
I'm unfamiliar with Hammer Blow... But Improved Sunder is tricky enough to qualify for that I approve of it. The important thing here is you make sure that the feat you replace Eagle Claw Strike with is at least as tough to get as Eagle Claw Strike.
