Yeah I have, I have seen a few of the JGHV bred and tested dogs. From my limited experience they are bit different than the NAVHDA tested dogs that I have only read about. The PP I have witnessed weren't the Racing high powered types, more blocky methodical searching dogs. The one thing you need to closely select for, is coat, from everything I know its not very consistant among the breed. There is a guy in PA that very active in the JGHV realm of PP, if he is interested choosing that direction of the type of dog.
