This has my attention. I vote for stainless steel screen rather than glass screen, the Glass Symphony bowl with glass screen was no good compared to the funnel bowl with SS screen. So adding a long path of ruby spheres wouldn't improve the performance? Also, it looks like the videos have ruby spheres, but the "gem vection" photo has clear glass looking like spheres? As for ceramic heaters, I've had nothing but great experience with them. Both with the Herbalizer and Glass Symphony. I definitely think ceramic heaters provide better flavor than glass. How do you plan to get the coil to fit more snug so we can get that temperature lowered down?
