I would not use pine or cypress. Conifers do not make good smoking wood because of tars and saps. I use muscadine vine on anything and everything. Sounds like you might be in Florida. Is pinon a type of oak? Have used pecan and walnut. Pecan is milder than hickory and walnut is too strong for me. Have never used any citrus woods. Might be good on chicken and fish. Do not use any treated wood or trimmings that have been treated with herbicides, miticides, pesticides, or dormant oil. Also, any wood you use should be very dry.
