I have a tru ball chappy boss listed in the free classifieds. Purchased May 2007. Std caliper head. $110 shipped. Trying to recover some of the cash i dropped on a now foolish purchase. Gone back to my short&sweet. Placed this post here also due to the fact that there's never much archery stuff in the classifieds.
