You know so much about the Kayfun tanks I wish you would write a blog about how to mix and match them for the effects one tried to achieve. It would be so useful. I know you're in the middle of moving but maybe after you're settled if you have time.
Believe it or not you can mix and match Kayfun, some Orchids, and original Silverplay and mix and match tge pieces and make a Frankenstein atty.
You can make the Kayfun mini without any chimney.
You can use a regulated 34 mm bell cap and use with tge Nano chimney. Holds 3 ml
Use the fill sized chimney and you can use the Steel Tank
You can use the glass Tank
You can use the M Tank. All of these holds 5 ml.
One member bought some 5 mm tubing to extend the Nano or regular chimney. Tgen be rigged up some way toput a 34 mm tall bell cap on top of an M Tank. He said Gus Kayfun had almost 10 ml of Juice.
I like tge old Kayfun because there is so many options and different bases so yoy can switch up your vaping style.
