Sup Tim!
Don't over call. Lots of guys do. If the toms are hened up the hens will want to keep the toms close and will call the toms back to them. If you have a dominant tom sometimes you can coax the others (Jakes or lesser toms) closer. I hardly call. If you are in the zone be patient and figure out if you are just set up a little wierd. Gotta be flexible in setting up and willing to move fast if need be.
Remember when we were talking about the ones you heard while in your stand? These do not sound like any call I've heard. Must be out of state/country turkeys.
