Yep the Cobb is sometime shy on the searing, that's what the cheap grill is for. But veggies, corn, potatoes, small roast and whole chickens its totally awesome.
You also need to WAIT until its hot enough to do what you want, rushing a meal on a Cobb doesn't work very good. BTW "loading up" a Cobb is only 8-9 charcoal brickets
