RE: MOUTH CALL ??
Don't think there's any mouth calls that clam to be the easyest to use , once you get use to having it in your mouth without gagging.
There all good doesn't matter if it from Quaker Boy , Primo's , Mad , or H.S.Strut they all havemultiple reeds and diffrent size's.
Maybe you start off with a small size that will be easy to fit in your mouth and then work your way up from there.
