Hmm, well genetics can be a lottery, so it would be hard to guess how big the dog will be. However, i would take a punt of saying the dog will be around 100 pounds. I think the Pitbull blood will deffiantly improve the dogs peformance/gameness, while also keeping your bandog smaller than your avergae Neo. I would guess your dog will around 100" give or take a few pounds, judgeing by the stats you gave and the 75/25 % mix.
