I start with lump charcoal in the weber chimney-- pour it into the basket-- give it a little shake.-- partly put it into the oven and pour in aprox two cups of pellets -- some will fall out the bottom (but no biggie.) This gets things blazing hot pretty quick. B&B seems to be the most recommended lump charcoal-- I've had success with cheaper brands combined with pellets-- If I wasn't adding wood or pellets, I'd prob use B&B
