Proven CD Inbreeding, wanting opinions

I will clarify why I said what I said. I would only reserve the brother/sister in my program for when I need to kick this down the road to keep the line going. If I have any other options for a line breeding I myself go that way. Others may disagree and I will not argue that it can work, it's just riskier than father/daughter in my book. That being said with the bro/sis being an outcross it is not as risky as 2 tight linebred siblings being bred. As far as tightening up on Frisco, you can do what you want but I am one of the only people you will talk to who's had there hands on Frisco and I wouldn't want the traits that I saw out of that dog. He was at my place for a week when he was about 8 months old and when we turned him out in the yard he was as skittish as a wild deer. He had to be cornered and grabbed as he ran by. Frisco had a beast for a father and I know a fellow who just got out of the dogs after running into him. When I saw how much Frisco was being bred after going to the east coast I was shocked. I'm absolutely not saying there weren't good dogs off Frisco but I know what I saw with my own eyes.
