I'd start out cheap. Listen to your calls and compare them to what you hear in the wild. You might not notice some of the differences right away, but with experience, you will learn what noise they want. Sometimes you do everything right, but they turn around and run in the other direction. That's a part of turkey hunting.

The best practice I have ever had was when I cackle back and forth with a dominant hen. They get so fired up and come ready to run you out of the area.

Last year, my first time ever hunting in Texas, I just grabbed a good looking place to sit down. First time of the year I pulled my calls out and tried them. They all sounded like crap. Thought I'd be better off just going home, especially since it was very windy. Next thing I know, two toms come in silent. Sometimes even when your calls are terrible, the turkey will still come to investigate.
