Do turkey boobs all the time
Inject withanything you like (I buy store marinades, never bother making my own)
One really good injection though, maple syrup. Heat maple syrup slightly in microwave (we keep in fridge,and won't go through injector) Then inkect like crazy. Again, put on rack first in kitchen, inject, then take out to beast.
Bacon strips on top are a plus, but not necessary.
I don't rub down, cuz it doesnt go through the skin as easy. If you rub, rub before injecting.
180 for turkey, which will be about 4 or so hours if you can peg 240 in the chamber.
Good luck Neil.
