I liked RO (orange bag)for my ribs/brisket/butts when I had the old Charbroil offset from HD. Used a vertical grate against the firebox door, then loaded almost a full bag of unlit, then a 1/3 chimney of burners to start a modified MM. Max I could get was 4 hours, with a little fire tending. RO here is only available from WalMart, so I tend to stock up with a dozen bags on hand. Haven't tried it in the new Klose but I will next. Checked the bag, and yes, it's Made in America, with a Georgia RO address. I too get some bags with small pieces which I attribute to rough handling, and an occasional rock. Haven't tried Barbecue's Galore yet, they have recently (last year or so) added a BBG brand lump, but the bag sez Mexico. Lord knows how that lump started life. An old thread id'd the Big Green Egg Lump as RO, with better QC than the orange bag, but twice the price. Lot's of mesquete here, just don't like it for the smoke.
Did a porterhouse tonight on the Weber with the lump RO and the smell and flavor were dynomite! Have been using KF in varying forms (old and new blue, competition, hickory) which are okay and much better than a gasser with no flavor. I like the KF for burn consistancy, but hate the ash buildup for a smoke. Fortunately the Klose Grill Chef has a great ash drawer so cleanout during a smoke is a snap. (unlike the old Charbroil offset).
