You already have some good surfaces. What i would do is ask myself, how either a copper or aluminum pot call would fit into my style and area i have to hunt. I have some awesome alum / copper pots and they are nice pots to play around in the right conditions. Weather / conditions you hunt in will help you decide what you need to use in chasing gobblers. A good waterproof striker is something you will need in your arsenal of calls. Nothing wrong with owning a copper / alum pot call of some kind, but for my hunting needs it's not usually in my arsenal of hunting calls until i have ideal conditions and the same could be said with most slates. Good luck with your choice of pot calls.. IMO...
