I generally use lump most of the time. I like to buy a lot when it's on sale.
Not really brand specific, but I have found that RO lump is pretty damn good.
I re-use as much as I can, too.
I will buy briquettes when they are on sale. We don't get the sweet sales up here in Canada as you do in the US.
I'm too far from the border to make any special trip and make it worthwhile.
This particular briquet is my go-to for a snake or fuse. I have gotten
11+ hours using it.
