Which one you guys using.
Which one brings in the big gobbler!!!!!
You're gonna get a thousand different answers buddy. Most make a pretty fair yelp. You wanna get fancy get a hand tuned custom call. You'll be able to do more. S S Custom Calls or Halloran are two good places to start.
Russell Beard long boxes or Richard Hudson hen boxes!! Both are proven killers!
Call some of the fine makers on this site and ask them to play their calls for you. Most will be glad to do so and then you can pick the one that you think sounds best. Good luck!!
