long overdue update. I went with the SQ14 and love it. Used with a 7.5 kettle for 8 batches and have since upgraded the kettle to 15gal. The burner has easily boiled 12gal of wort. I do regret not going with the double though, because I have since fallen in love with partigyle brewing and the 2nd burner would be a huge time saver.
