I haven't used him. I've sure been considering a few of his sons but haven't pulled the trigger yet. I like his proof numbers across the board other than his calving ease. In my experience anything over 9 is usually looking for trouble.
If you are looking at his sons, Bruno has been the hot one as of late. He is only a Genomic bull but is in the Judges Choice lineup at ABS and looks to be a great bull someday.
