As you guys know, I am mostly a predator call turner. As such, I turn calls with one lanyard grove, usually in the body of the call. Even if the call is two piece, the mouth piece is either glued in or very tightly fit in with o-rings, and they rarely come out. But for you guys that do the duck and goose calls, I have a question. I have always heard that the call should have a lanyard grove in the body, and in the insert, so you don't have to dive in the lake for part of your call. I have noticed, while viewing all the beautiful duck and goose calls you great turners are making, that this is not always the case.
So, now you see the reason for the post. What do you think? Should there be a lanyard grove on both parts of the call, or is one sufficient? Reasons for your position.
