We had a daughter of a 75% Skull son that was desperately game and an all around quality bitch. We also had a direct son with an outcrossed bottom side who was a big, powerful, SOB, and also ultra game. So, unlike many lines I have seen and utilized, the Skull dogs we were given were both deep game, which most people don't expect out of Eli based stock. Try to see if you can get 2 out of 2 good ones out of any bloodline and it will be hard to do. These were both gifts from other breeders, and perhaps we were lucky. Nevertheless, my opinion is favorable and I do not have a drop of this blood today.
