I started out turkey hunting with a Roger Lathram Penn's Woods box. I've tried a bunch of boxes down through my 36 years of turkey hunting. And, this is just my personal opinion. But, to me Lynch style (Cost) boxes sound good in the house; but, I've carried both styles to the woods. To ME, the Turpin style sounds more turkey than the others! I've carried both to the woods at the same time and played both. That is just my opinion. I'm sure others say different! And that's O.K.. All of us have different sounds that we like! Turpins, Turpin styles and wingbones go to the woods with me. You can't go wrong with a Turpin from Steve Turpin, Dan Harris, Richard Hudson, Russel Beard or Doug Morgan call. Mike Lapp, Matt Fulkerson and Ed Jenkins make some good ones as well
