I like the lump wood charcoal too. But I struggle to get the heat right. It’s either a fireball or nearly out. For smoke I add wood chips soaked and dry. That way I can play with different flavours.Plus 1 on the coals. I thought Weber coals where a step too far and you where only buying the brand name. But no they do last a long time. If you have baskets to keep the coals together they will give good heat for three hours no problem. The other thing we have tried is catering grade lumpwood charcoal. You get an amazing smokey flavour and some fierce heat but they vary a lot between bags. Some lumps are just right some a huge and need the attention of a hammer and other spit bits everywhere.
