1. BBQ/Smoking: Both Paul Kirk books
2. Grilling: Weber's Big Book of Grilling
3. Outdoor Cooking: How To Grill, S. Raichlen
I love cook books though, I also own Smoke & Spice-Jameson's, BBQ Sauces & Rubs-Raichlen, Weber's Art of the Grill, 3 of Emeril's books, 2 books by Justin (no last name necessary).
That being said, I have used them all occasionally, but don't use them a lot. Will use them when I get on a kick that I want something "different."
