Glad to know you had thing up and running quickly. I dont use the cool down. When my set temp is hit, I use another probe 'just to be sure', pull it, double wrap in heavy foil, huge beach towel, then into a cooler till eating time.
Regarding your leg quarters, you can crisp up the skin under a broiler or on a screeming hot grill. Some folks use a propane torch with a fancy head on it.
Enjoy!
