I think there is a family of dogs called Georgia curs that are a cur pointer cross. I don't know the percentage of each but I hunted with a couple. They were hot footed and had the bite. They were stupid rough but definitely weren't bashful. They zig zag hunted and at a real fast pace. I thought they were nice dogs myself. I know they started some sort of registry also for a hound/pointer cross that they were competition coon hunting. Said they wanted to quiet the hound and speed them up but needed the treeing ability of the hounds. Again I don't know what the exact percentages were.
Sounds similar to them Campbell curs out of Georgia.
There was a guy that used to be on here that I hunted with a couple of times and he had an outstanding pure GSP. He told me he was able to get her because instead of pointing she would just try and catch the bird so she was a cull on birds. Man she was a ball of energy and she would go. Very nice dog.
