you can hunt with what you hunted with 20 years ago and if that's all you are gonna do then it will work. But like Nodog said, some of us shoot a lot and wear out things.

I buy probably more bows than most, and shoot more than most. I replace strings and cables on my competion bows at least four times a year, and two times on my hunting bows. I'm always trying to achieve archery greatness, by competing against the only person I want to beat. My self.
But then again not every one is an archery addict!
