Was checking out brands and cost of pellets and have a couple questions. Home Depot had very little pellets of any kind but Lowe's had a lot of Pit Boss pellets. They have a 40 lb bag of Pit Boss Competition Pellets for 15.00 and a 20 bag of apple for 10.00. First how about the quality of Pit Boss Pellets and second whats Competition Pellets? Third why the great price on the 40 lb bag? I have been a Kamado smoker for several years and quite frankly had a hard time distinguishing the difference between the different woods! Is there a big difference in the different woods in pellet smoking?
