E-Z estrus all the way for me. I love his cow calls. I have 3 of them and have had great luck with them.
I am also a huge fan of his casper turkey diaphragm. I usually put several birds into the dirt with the last thing they hear is a raspy note from "the bar fly" LOL me and Jason go back and fourth on the name

I also just about got a boot out of the booth this year when he saw the new berry pro bugle in my bag

Sorry jason
