Old School or New School?

I recently read an article about the usage of old time calls. You know, that wingbone call or old box call that is 40 years old and held together with bits of tape and string. What is it about these calls that make them so special? Is there a story that goes along with them or is it nothing at all? Do you have more faith in one than the other? I think more times than not, it all comes down to what the call has produced in the past. Why go with the new one, when the old one called in that slammer you bagged last year? The article I was reading questioned the sound of the older call vs. the newer ones. Personally speaking, I have quite a mix of new and old in my vest, mostly because I want a variety of sounds. For a while there I would try to get every new call possible, yes I am a sucker for good marketing... But time and time again I sat at the base of the tree pulling out my slate call from 10 years ago that I called my first bird in with and more times than not, that call gets the attention of more birds than any new call(which I needed a loan to buy). When you think about it, calls are a relatively simple thing to construct. Every so years I find that a call maker will venture into a new area, with new material and build something different, cool. But for the most part, many of them are the same. What's the point here? Stick to what works, but next time you're sitting in the woods or on the couch practicing your calling, look at what call you choose first; which one do you have more faith in?
