Revisiting an old thread here, but after much experimenting, I have settled on the Southern Succor rub posted often on this forum, and just using that rub alone seems to add to the woodsy flavor. On the 18.5" WSM, I like to use at least 5 tennis ball size chunks (buried) of locally harvested hickory. Creosote seems to be non-existent too. I still use Royal Oak lump, but by placing a single layer of briquettes on the bare grate (around the wood), it keeps the smaller lump pieces from falling through.
Bottom line is that I am happy with the results.
I plan to inject pineapple juice into a butt one day and see what that tastes like.
Cheers!
EDIT: For what it's worth, I found this information while looking at some dome thermometers...
Low heat cooking – Pork shoulders and ribs cooked professional barbecue chefs taste better because of the take in preparing and cooking at stable and low temperatures. These temperatures are typically below 300°F for the of time to create that flavorful bark and balance in smokiness, texture, and moisture. When cooking with wood, lower temperatures increase your volume of smoke.
