Mike Yingling's copper calls are probably the best deal out there on a copper call. I have a copper call he made me that has a small slate on the back for light clucks & purrs. It's pure turkey & has become one of my favorites. If you want to stop the striker wanting to slip on the copper surface get you an acrylic tipped striker. I use the Cane Creek Cottonmouth on mine. It will run good even on those damp mornings with a heavy dew. Before I starting using the Cottonmouth striker I had all but given up on copper calls because of the striker slipping.
