Hey Steve-since it seems you re not shutting down North Bay Game Calls, I want to ask you about the dweeter whistle. Can you make that so that there is some space between the end of the stopper and the end of the barrel? I always have trouble with calls that have the stopper like that. What happens is that as my lips get chapped or cold, I have trouble sealing it, unlike a regular duck call. I do like the whistle, it works well on the teal and pintail in my area.
