Most people I've discussed Skull dogs with tend to like the Skull x Scream dogs. Some kept them tight, some crossed with Six Bits, or Bolio blood. Most said the same though, rough, hard biting, barn stormers, just like most are known for. Though they seemed to think the Scream cross added more gameness and produced in higher %'S. Though I do follow and like the Eli familes I tend to use it more of an out. So I really can't offer more insight than that.
