I'm likely on the anal side when it comes to adding weight. Maybe you've done it already, but I would spend some time figuring a way around the tail mounted servos. Possibly going with a single (center mounted?) pull-pull setup?
Just a few ounces back that far can cost you several times that amount in weight required to balance them up front.
