If you like using lump for the minion method (which I do), they make a great kindling bed too. In my WSM, I start with a bed of the little tiny pieces (and I really don't worry about what falls through), then add some mid-size pieces around the circle leaving a hole in the center with just kindling, fill in the gaps with some more of the tiny pieces, then make pyramid structures around the center with the large pieces (the longer the burn, the more pyramids I add), and then fill in even more gaps with the "kindling". Then I dump my hot coals in the middle and let it ride.
