When doing both, I use straight Hickory. Mesquite is too strong IMHO (even when used 50/50 with Hickory) and is not allowed to play in my back yard any more.
Try this: yanno those Pork spares cryo-pacs? I buy mine at Sam's. When they get trimmed down to just the ribs, what to do with the extra meat? Grind it, mix it 50/50 with hamburger, make it in to meatloaf, and smoke it with Hickory.mmmmmmmm
