Who buys the small bags of cowboy? The 20# bags I have bought lately have had a bunch of fist size or better in them. I'm not familiar with the red bags R.O. But the green bags have been very good lately. The R.O. Seems to be less dense than the cowboy and thus burns faster. All just my opinion but it comes from a lot of trial and error!
