A mouth call would be my first choice... the Alumistrut Viper, (which I can't seem to find anymore), and I'm kinda fond of the QB Pro Triple or Kight & Hale Cutters.

My Slate call fav... a 3" custom slate from an ol' timer that makes them one at a time right here in central PA, and a little square slate called a Broadcaster, 'cause it makes some of the sweetest early morning limb talk around.

Box call fav... a little mass produced double sided box called Perfection, a buddy of mine gave it to me years ago and for some odd reason, Gobblers love that thing. Especially on windy days.
