My favorite and only call I've used in 7 years is my home-made wing bone call......hasn't failed me yet, has a slightly different sound and pitch. I also don't over call, I've learned WHEN to call as well as HOW to call and when NOT to call. It's like most anything.....takes observation and practice, it's really not rocket science and most anyone can do it, the actual calling doesn't normally need to sound that great...I'm proof of that!
