The Balcony overhang starts quite early in the Mezz, and it drops into the top of the stage by around rows G/H (although how much this affects the view depends on the show and set!) I also think some of the back seats can become restricted if people in front lean forward, so rows E to G might be good value options!
I'd agree with haterobics that the front Balcony could be a nice choice (price permitting) and people sitting there tend to like it. We have some photos from the front row of the Balcony and mid-rows of the Mezz here, if you prefer real view-from-seat references to help you decide.
