I will at times put a couple kingsford charcoals in with my wood when doing ribs. I don't do this for myself,but to impress some guests.
I can't tell any difference in taste, but haven't tried the TQ on my big meats to see there.
Smokin' has told us to keep good notes and try one both ways. That way we know for ourselfs what we like and what not to do again. Seems simple enough!
