if you dont know which or what, pick a call(one that your good at) and start off with some soft yelps. if you get a reponse give a couple more so the tom can zero in on you and shut up. if you done your scouting, an know you got turkeys around, somebodys gonna say somethin. im new at this and i am gonna rely on a decoy or two, but i aint gonna call too hard (i hope)
