Basic double reed and a backup slate.
Used MAD stuff way back and worked fine.
Think the newer stuff not as good in quality.
Proly order a custom slate.
I really liked the original MAD single and double reed red tape calls. Wish I could still get them. Haven't found a replacement yet that I can run as well or feels as comfortable.
About all my calling these days involves a Harn Final Summons box and an H S Strut 360GT with various strikers. There's also a push button box on the fore end of my gun for close in sweet talk and I'm getting better at voice calling.
