I try just about every friction call I can get my hands on but hands down the best I have every used for me personally is a Cody World Class slate. The Cody woodsman is a great call as well for a much more reasonable price tag.

Running a high end call and learning to use it correctly does make a difference IMO particularly on some of those older public land turkeys. Yes at times a squeaky car door will call them in but at times sounding exactly like a wild hen makes the difference.
