I like cordovan a lot, but the Bateman I got at 3rivers had the elastic strap. That thing would fly off my hand all the time. I would get the one with the leather finger hole on it.
The Cavalier elite cordovan is the best release I have tried yet. The leather and backer thickness was ideal for me. However, I didn't like the metal plate. The way I anchor it would scuff my cheek.
The Fred Eichler tab looks great. Anyone know how thick it is? I would love to get a pic of a side view of the layers and maybe have someone mic it to see how thick it is overall.
The Black widow calf hair is excellent, but the hair comes off them way to fast for me. The supper leather is nice, but leather doesn't last like cordovan, and it is kind of on the thick side. I hear they used to have a cordovan. I can't find one, but I bet it was a great tab.
I am shooting and loving the pack tab. Very adjustable to your personal needs.
