My feelings are, after doing about a dozen your size, is cooking at the higest temp, the better. The reason is moisture. When I cook at 225�F, there is always much more water and grease to dump. And, much of our conversation aboout smoking turkey is breast moisture, or the lack of it. If there was a way to raise the temp to 325�F, I'd do it.. Maybe start it at 200 during the initial smoke and then raise it. One thing I've been doing lately is to start a 225 in the smoker for about 1.5 hrs to get good smoke flavor penetration and finishing at 325-350 in my Weber Genesis. Good crispy skin, goood smoke, nd good moisture.
BTW, welcome to the forum
