Probably the best advice I can give you is to learn the basic yelp. More turkeys have been killed with the yelp than any other call. Once you master the yelp, then go onto the cluck. Invest in a good video with lots of hunts and learn from the pros! Primos has a great series of DVDs and some of them have as many as 20 hunts on them. As far as personal preference, I like the Cuttin' Hen by Quaker Boy. One of their easiest calls and most popular calls. Boy does it sound good.
