I have two seasons of duck hunting behind me and I'm hooked. I would like to buy some duck calls and learn how to use them. I would prefer to buy a duck call that lasts about 30 years even if it costs a little more. Mike Pinto suggested Macks Prairie Wings. I went there and they had almost 200 calls available. I've read a little about them, but would love to hear some ideas from my fellow forum members. Please tell me about your favorite calls, how hard they are to learn to use and the maintenance requirements for them. Thanks in advance.
