Turkey queetions

I am going to smoke a small turkey on my YS 640 tomorrow. I have read the recipes on The Sauce site, have spatchcocked it and am brining it now. I intend to smoke it at 250 for an hour and then at 425 until internal temp is 165.
Question 1: The turkey is 11.75 lbs. How long will it take to cook using this method?
Question 2: Should I tent the turkey with foil at any point in the process?
Question 3: What flavor pellets should I use for a turkey? I have several different bags to choose from.
Thanks.
