The longest I've ever smoked out of one bowl of Starbuzz is 1 1/2 hours. That's as much as I would want to smoke. After that I get tired of smoking or bored. It's funny that you mentioned that Starbuzz is temperamental. I wrote a review on a sampe pack of Al Fakher I got. I experienced your same situation, but with Al Fakher. That's why I gave it a crappy review. I've never had this problem with Starbuzz. It was so starnge that right since the beginning of the session, the Al Fakher was overheating. I packed it the same way I would with a bowl of Starbuzz, and yet, it couldn't handle two 30mm Golden coals on a small phunnel.
