Vapor concierge
So, apparently, I think I've proven you can pull too slow with it.
I have to pull just fast enough to initiate 'whistle' mode to get good vapor density.
Is there anything that can be done about the whistle? can i like, bees wax the joint? that seems... no. not right at all. sprinkle kief on it?
On my old cloud I took a tissue and stuck it in the bottom hole to drown out the whistle. It restricted the air flow a little bit but drowned out most of the whistle.
