You least favorite surface

[TauntoHawk]

I've only tried one copper and I never liked it enough to even take to the woods.

I love ceramic prefer it over slate it's not so weather finicky.

Copper.

I have a titanium Mad's call in plastic pot. It is killer!

I own the same call, Mad's "Super Titanium". It was the first pot call I used to successfully kill a spring gobbler. I still carry it in my vest. It really does sound good. On to the OP question. I don't really care for ceramic or copper.

I'm all about a slate with popping crisp clucks and an aluminum with sharp raspy yelps

My least 2 favorite surfaces would have to be bead blasted glass and blasted aluminum.

That being said ceramic, crystal, and copper are without a doubt my favorite.

I haven't found a surface I dont like in some form or another. There are many individual calls I dont like but they all have the same playing surfaces of my favorite calls.
