RE: Aluminum calls
I have been using a MAD Super Aluminator since 1997, and love it. I have called in numerous turkeys with it. I did pick up a couple of new calls this year though that I think sound just as good. The Primos Crystal Freak and the MAD Heavy Metal. I carried all three calls this year and all three produced a gobbler for me or my hunting buddy.
Try one if you don't like it try something different. Trying new things is half the fun of turkey hunting for me.
