Double Weapon Attack and Rapid Strikes

[Jasonft]

I'm interested in this one myself. Fantasy China campaign I was in until Feb I was the party tank and was doing pretty much exactly the trick described above. If I was breaking a hard set rule I would like to know.

Of course I did have Weapon Master, but it was more or less the same trick. I thought I was fine so long as only one of the weapons/ hands was affected by the Rapid Strike.
