This is why you need to call Parker Bows

I called them 2 years ago with the same question. They told me that their higher end bows are a little lighter due to machining, are more expesive to build due to the machining costs, camo on the cams, but that the bow they sell the hunter mag has just as tight tolerances, bla bla bla. The guy I spoke with said that they would make more money if I bought the 35 UL but that If money was an issue I would be just as happy with the hunter mag. I bought the hunter mag, several hunts and 3-d shoots later I couldn't be happier. great company, great bows, no hype.
