Rubs contain a lot of salt. Salt tends to draw out the moisture if left on too long. I try to never rub anything for more than a couple of hours. I do turkey boobs all the time. I inject them with what ever I have and smoke to between 165* and 170* at a temperature of 275* to 300*. I have never tried bacon strips on the boobs. The problem with turkey boobs is one is never enough for my crew, I have to do two to get anything for lunch the next day.
