[Smokin' Gnome BBQ]

I have never really had any success with chicken and wanted some input. I generally marinate in Itailian dressing overnight, move the chicken (thighs) to a foil pan covered with foil for an hour and a half on the smoker and finish on my chicken grill with a little smoke and high heat then sauce with a sweet mix of sauce, juice and some corn syrup. bite through skin,trimming and presentation dont seem to be the issue. Im not sure if I am even in the ball park with this, what do you think?
