I use both lump and briquets.
However, I probably use lump about 75% the time. Maybe more...
I hated all of the smaller pieces falling thru and messing with the sweeper blades.
So, I decided to make some baskets of various sizes using EM (expanded metal).
If you're handy, I highly recommend these.
And, if you're not so handy, I recommend a piece of EM on top of the charcoal grate.
It will make using lump much more enjoyable, and it's not expensive. Very easy to do.
Be sure to use gloves when working with EM. It will cut you like a razor blade.
This one is the same diameter as a SJ charcoal grate.
I call it the polar vortex...
This one is half a charcoal grate for a 22" kettle.
This one is the same size as a Weber basket, only a bit taller.
And, a couple years ago, I repurposed a beat-up 22" kettle.
I cut a ring out of the bowl, then proceeded to make various shaped and sized baskets.
