I agree that one should find "real" charcoal of actual logs. Not easy to get, but worth it, you know you are not purchasing an engineered product designed to burn long enough to cook, but not long enough that you don't have to refuel. I'm not accusing the charcoal companies of doing that... 'just saying.
When I smoke-cook meats, I use real wood of course, and right before I know I will be done, I throw in a couple of extra logs, but on the grill, not in the fire. The fire is hot enough to char the wood, but not enough to ignite it, just like real charcoal is made. In this manner, I then have the charcoal I need when I fire up the bbq.
I still use gas, but only when cooking for the kids and need to get the chicken cooked fast, or am limited by time. Else, I like the old fasioned charcoal method, and like to drink my beer, or wine while the fire heats up.
