I' m still beginning and doing lots of practicing (when my wife isn' t around

or she' d throw me out of the house [:@])!!!!
I know people here have answered something like this before, but when you store your mouth calls in Scope, do you cover them completely, put a paper towel in bottom of the snuff can and wet it with Scope, or what??
Also how do you know when the call' s diaphragm is wrinkled too much and needs to be replaced??[X(] Or how do you know when to replace the call in general??
