I did my first butt yesterday with straight fruit wood. Now, you have to understand I'm a"hickory nut" sort of speak. I love the smell of hickory smoking BUT the aroma's coming out of the WSM using the fruit wood alone were, to say the least ,intoxicating. Used apple and maple. I don't know if I'll ever use straight hickory again. Anybody take a huge stash of hickory sticks in trade???
