Qnorth,
We could not tell an appreciable difference in moisture between the two, but the brined bird did pick-up nice flavors from the brine - used SmokinOkie's recipe. Let me say however, we got started late and only brined the bird for about 9-hrs which was not long enough (I've heard anywhere from 12-48 hrs recommended), but it was time to get it in the oven. The actual smoking process was hindered a bit as the breast temps got to 160* after about 4+ hrs, but the leg/thigh portion looked a little raw still, so I left the birds in and reset the breast probe temp to 180* which is the old recommended temp I am used to. Needless to say, the breast meat was a little dry, but not too so - still very edible. The leg/thigh was then done enough. Thus my reason for trying a "quartered-up" bird next time - then I can take pieces out when done & leave rest to continue. Since my process this time was a little flawed, I can not say whether the brined bird was truly worth the effort, but there are many folks out there that swear by brining and I'm not going to go against them.
