Can I mix a lot of different smoking woods together?
Yes, you may mix different species of wood together for smoking. If the combination tastes unbalanced or muddled to you, just pretend the wood chips are from a rare Amazonian hardwood species, and it will suddenly taste amazing, even to the fussiest of "experts". Better to obsess about the quality of the meat itself, or maybe even the characteristics of the wine.

P.S. sorry about your trees, that must have hurt.
