I use the red bag for my kamado, and have had no complaints at all. After about ten bags, I have not found a single rock, piece of insulation, or other trash like I find in most of the other lumps. Mostly good-sized chunks of lump, very little square scrap lumber. I got a chunk nearly the size of a football in my last bag, actually had to break it up.
The red bag is made in America from American hardwoods, like oak, hickory, and such. the other color bags are made in other countries from tropical hardwoods. I prefer native wood, and American regulations on what can go into stuff over the third-world-produced stuff, myself.
...Half a yard full of crap to cook on like everybody else...
