@Gary-Airvape I'd just ask that a lot of thought and testing be put into the dosing capsules before launching them. Yes everyone wants it, but in convection vapes, capsules rarely work ideally.
Focus on isolating the airflow Through the capsule (not around it) without introducing too much conduction.
A solid capsule wall with some sort of seal gasket near the top rim should help to ensure air is forced through the capsule, while leaving an air gap between the crucible and capsule wall.
If it isn't done very well, there isn't much point in capsules when it comes to convection.
Edit: also please make capsules easy-open. Not like the Crafty aluminum capsules that are hard to open and easy to deform
