For anyone who has used the Herborizer bowl and heating element with a custom GonG bong: In both models of the Herborizer, the heating element sits at a perfect 90 degree angle. This is because the tube is a stemless and the sphere receives the bowl at the top. However, in many GonG bongs (including the ones that I own), the joint is at an angle. Has anyone who has used the Herborizer in a custom GonG bong had any issues with the angle of the joint and the weight of the heating element? I like the idea of the hands-free Herborizer, but I don't want my unit to tip.
