Sled,
Sorry you were not so pleased with the results.. go with the gut and use the flavors you like best. If it's you're own rub even better.
I sent you a PM with a wood source I located in Nassau County but have not used yet as I still have a lot of wood from Prianti Farms in Dix Hills where Phil recommended some of us LIFO's go...
You may get a little extra help by picking up a few firebricks to put in the bottom of the cooking chamber to help retain some heat. I bought some at Jetmore in Wantagh for $20. 4 bricks per box. About 4" x 2" x 9". I then saw them for $17 as the Ace True Value in Bellmore. Same brand.
