I'm headed out that way on the 11th. Most likely will spend the majority of my time on the Madison around Three Dollar Bridge.
The Firehole was great during middle June, but it likely will slow by the time you go (July 11). The water was already warming when I was there.
The Madison was slower than the Firehole (and also warm), but fishing it outside the park may be better. I didn't try around $3 Bridge, but certainly that's a favorite stretch.
Best flies for me: #12 black wooly and/or #12 prince. Both best right in the fast water.
Have a great time, and bring back some photos.
