I like 2 sided calls and am starting to look for one with gray slate on top and am open to suggestions about what's on the bottom. Any recommendations for the bottom surface and a pot call maker? Most two sided calls have gray slate on the bottom because it's easiest to get gray slate in the smaller size.
A now ex friend of mine got in a nice green slate over black slate that sounds very nice. I will try to get name of maker for you. Edit, that may be glass/crystal on top with green color under it, sorry about that.
This is the call, I was surprised how big the second playing surface is. https://tripletoecalls.com/shop?olsPage=products%2Frendezvous&page=2
Any other recommendations?
Tony Reynolds makes some great two sider's, I don't think any are slate on top thought but he makes a crystal with aluminum bottom that is a great caller.
