This is my first season, so they're all new to me. I'm kinda a call nut. I've coyote hunted for years with hand calls. I've always loved a good hand made custom call. So with that said, I've bought "a few" since January. I also stole a old one from my Dad that I'll be running this season. It's a old (probably 40 plus years old) all wood Thomas Standard. Thing sounds amazing. I also really like the Calef Calls Kamikaze single reed and Shocker; along with the Tim Grounds D Overhauler. Those are the ones I plan to use, along with a whistle. Been practicing since January. I keep the calls in my vehicle and practice a little every day just about. It honestly took me months to get a good quack down. LOL I'm really looking forward to the season.
