@Mushroomturtle my draw speed is probably pretty fast. I'm used to quick 4-6 draws on the glass symphony, I'll try to slow it down and see if I get better results. My bernzo max flame does look a bit small, the tank was about 50-75% full in the pic. How is it compared to yours @duff ? I have a video of heating and drawing on it, but I figured I wouldn't post it unless my flame looked good.
