I don't know that I've ever had a call that didn't stick. If you blow your call enough and it is cold enough, it will get enough moisture under the reed to stick. I don't think there is a such thing as a call that won't stick. If there is, I sure don't have one. What I do when it starts to stick is, pull out the insert and then pull the reed back and blow under it. This will get rid of most of the moisture and any debris that may have gotten under the reed. Or I take a napkin or part of jacket and wipe the moisture out from under the reed. It works for me.
