I have tried RO (red bag) a few times I just bought a bag about 2 weeks ago since it quit snowing here in Ohio. I find a lot of tiny bits. The last bag I got had about 6-7 good size peices. The rest of the bag was shake, tiny little bits that fall through the grate at the bottom of my kamado or grill.
I have had better luck long term with Cowboy but I am likely going to try RO food service (GFS brand) because there is a GFS on my way home from work. hear roumors there are more bigger bits.
