I marinade, dry rub, and then sauce it on the grill.
Layer the flavor, baby.
Low and slow is the only way to go.
What kind of marinades and dry rubs do you use?
I keep marinades real simple. I don't have a recipe per say but the basic formula is 3 parts oil, 1 part acid and then whatever herbs or spices you want to use to compliment the meat.
I found a great book on cooking that is nothing but a list of what goes best with what as far as herbs, spices etc

I usually pick a few herbs and spices out of the lists to add to a marinade.
As far as dry rubs I buy some and make some myself I tend to favor savory/ spicy over sweet
here's a good place to start
Simple Dry Rub Recipes That Work Wonders
Sauces are really fun. Most people stick to a basic tomato based BBQ sauce. They tend to be sweet for my taste.
I have a couple that I like to make
Chipotle Lime sauce
1 small can of chipotles in Adobo sauce
I use a stick blender to puree them seeds and all. You can remove the seeds if you want less heat.
The juice of 3 or 4 limes
some light oil like canola or walnut
Salt, pepper, onions, garlic, ancho, cayenne and smoked paprika and some honey or brown sugar.
I can't tell you amounts as i just wing it.
I also do a tangerine, maple, habanero that rocks
