We shouldn't even discuss quicklights lol. They're bad period. As far as natural coals go...one month the worst brand becomes the best brand and the best brand becomes the worst. I.e: titanium's and Cocourth were fantastic. Currently titanium is experiencing some blacking out issues and Cocourth just relaunched it's product after a massive fail a while back. I just switch brands every few months because there will never be a coal that is consistent 100% of the time unless someone discovers a way to manipulate rainfall and crop yields lol.
