You can match up slate with about anything. I have made around 30 glass over slate this season alone! I like to make dual purpose pots, they offer so much more to the hunter then a single sided pot call, especially when you have two strikers to get four distinct sounds from one pot. I have made ceramic over slate, titanium over slate, crystal over slate copper over slate....and the list goes on. You will find a lot of call makers hereon OG that will fit the bill.
