Pick just one ??? thats a tuff call, get it...HA !! tuff call !!! I kill me HA HA HA !!
My fave sounding would be my tube call but it takes practice to stay on top of it, a slate is pie to run & can easily do a variety of sounds, diaphrams are great but I cant do a gobble on one...this would a tuff decision.
Probably a WoodHaven classic V3 or Red Wasp, I can do most any sound I need plus they dont take up space or rattle & klink when ya walk.
