My compliments on your work, Bill. I looked at your website, and you are using some original and creative elements in your calls. I foresee owning more than one of them in the near future.
I noticed that you are bundling some calls in a package, which is a fairly novel concept. What I believe would be useful to hunters and a selling point for makers is to do pot combo kits with similar woods. It is useful for any hunter to have a slate, a glass, a ceramic, and/or a copper and/or an aluminum call in the arsenal in addition to a box call or two. You don't see many makers pushing twosomes and threesomes in pot calls at a slight discount. They would make great gifts for others in addition to one's personal use.
I'd like to know more on your website about the sound properties of the wood combinations that you've chosen for the box calls. Those are interesting combinations and the finishing work that you've done on them is very nice and fairly priced, IMO.
