Doing my third pizza cook, having trouble betting past 525. PS, legs down. 3 bricks on that, pizza stone up in the dome. I think the thermal mass of the bricks is a problem. Both vents wide open, glowing red when I look through the bottom vent. I saw a rig with a wire rack to get the stone up in the dome, set on top of the PS. Maybe that will work better than the bricks. Any suggestions? Thanks.
