The Bella add on created a great flavor, and it lasted well throughout my 10 hour smoke. I have ZERO complaints about the flavor of my cooks using Smokinlicious wood chunks, and will continue to use them. For me, the (Pit Boss Barbecue Hardwood Pellets, Apple, 20 lb) apple pellets were a successful experiment for boston butts. Got great feedback from my sample-buddies, as well - they come out of the woodwork when smoke starts to escape the garage - like somebody turned on a silent alarm ;D.
