19 years later - I finally wore out a bow!!!!
My official "winter" bow is a 1983/84 Browning Explorer 4 wheel compound. I used it because I could wear heavy gloves and still use fingers. I was practicing when I released a shot and was showered with small black pieces of black epoxy. The laminate at the upper axle finally separated from the wood.
Now I have a legitimate excuse to buy a new bow. I've been asking around and can find no one who has had a bow long enough to wear it out. I feel proud.
After reading PA Bowhunter's review on Hoyt bow engineering, I wonder if it's even possible to wear out a bow in a person's lifetime!
