I use apple, hickory, and oak the most by far, cherry would be a distant fourth.
I use apple for all fish, and some cheese.
hickory for all jerky, and some cheese.
Oak and a bit of cherry on most ribs, butts, brisket, etc...
I usually try to keep a 120 pack of each of those on hand. I do buy other woods such as maple, pecan, alder, etc.. but usually only 48 packs at a time.
