Go get you a Primos Long Hooks, easiest mouth call I have ever used. Sounds great and I've called in all 4 sub species with them.
^ 2nd that! Love the primos calls, I also use the HS Strut raspy ol' hen as well.
I like to say I am a decent caller with my mouth calls, but I am not as versatile with them as I am with my slate. I cant purr with my mouth calls and its becoming very frustrating. I keep practicing and trying but no luck just yet. Any suggrestions?
