I think 8 F was a good move. I'm between 9.5 and 10 on Brannock, and I wear 8.5 or 9 in AS shoes/boots. On the Fly in SF also has a complete set of fit models for the Handgrade lasts. I posted pics of them here. Btw, I ordered a pair of AS premier shoes for a friend from AFPoS a few weeks ago. Service was great. Thanks!
