I did lump in mine once. Didn't really care for it. Burned too hot too quick.
I did a half and half of RO Briquettes and RO lump one time also and it was a little better.
You could use lump but like already stated you will have to adjust cook times because of the temp increase. Also don't be surprised if you had to add some fuel. Try it out and see
On a side note: I burn Stubb's Briquettes in mine regularly and have great results. Never actually used KBB in it so can't speculate on a comparison between the two.
