I know I should be asking this on a BBQ site, but I wanted to hear what you guys think. I cook with my Weber Smokey Mountain several times a year, and so far have only used Kingsford briquettes. Very good results, but sometimes in cooler weather I have a little trouble keeping the temperature up. I hear that lump charcoal burns hotter, so I thought it may be a good idea to use it or maybe mix some in with the briquettes. By reading some reviews people generally like it, but very inconsistent quality no matter the brand. Very small pieces, rocks and other debris. What has been your brand-specific experience?
