There's only one thing I believe from Hank Parkers mouth. That was his favorite joke. "How do you make a small fortune having a small race team in NASCAR? Start with a large one." The man is a used car salesman that got lucky fishing. Him and Jim Shockey are both self promoting liars. Don't fall for just anything that some moron from the idiot box tells you is good. They are paid hansomly to promote these junk items like Tinks 69 and Shwackers. Every year there is always someone on the idiottube promoting this or that claiming it's the best thing since sliced bread and you absolutely cannot be successful in the field without it. It's hilarious how the American Indians fed their tribes with whitetail and elk long before the expandable broadhead, or hell, even metal broadheads were even thought of.
