Pellet Head from 2012, bought a used YS640, fully updated to 640S. Also have a PitBoss Vertical cabinet pellet cooker, and a UDS. I love cooking for my Church and others as I can. Also A Master Judge with South Carolina BBQ association. I will work on updating my profile. I also blog a lot of my cooks, as a reference for me, and sharing information. Can I post a link to my blog?
