I only burn lump in my BGE, other cookers I sometimes use briquettes. The reason I won't us it is the amount of ash it produces and can fill in places that you wouldn't want filled in for air flow on the BGE. Also, I don't want to risk binder resin to embed into my ceramic pores and become a permanent fixture if you know what I mean. Just like you never want to use lighter fluid.
