Not at all, I did the same thing....mouth calls are much more suited to a single individual than any other calls. Mostly because of the conformation of a persons mouth. Each persons pallet is a different size or shape and peoples tongues and pressure differ greatly. The biggest problem is not only finding one whose shape fits your mouth, then which one has the appropriate tensions to make the pressure youse sound the best, then the final step is appropriate instruction and tons if practice. In my case I found the Matt van cise pre cise three call pack from mad calls. Or the Scott Ellis signature series work the best for me. I've tried tons of customs and those have sounded the best.
