Cowboy was my only choice for a while in my area. I didn't like seeing wood flooring cutoffs in the early years (about 4 years ago), but it still burned well, although a little sparky. My Wallyworld started carrying RO, and had it on sale for $5/8.8# bag last year, so I bought a bunch. Saw that Lowes had Cowboy in 20# bags for $9.99, so I bought a few of those bags. It's been fine, lights as easy as RO for me, and now that it's not a bag of hardwood floor cutoffs, it has similar makeup of larges and dust as the RO. I use veg oil and a paper towel with all my lump. I'm thinking you may have gotten a bad bag? On another note, the worst lump I've gotten has been an off brand that was mesquite lump. I thought it was good in the beginning, but talk about a strong smoke flavor. It took over everything I cooked on it.
