Update Bump:
One happy vaper here!
I've made several new builds and or re-wicks now, and it's all good!
Getting a great vape out of my Vapor Flask - Kayfun v4 combo.
I completely gave up on the method I saw on You-Tube; combing and fanning out the tails, cutting them precisely to tickle the deck.
Thankfully the way that works for me is much quicker.
No fanning or combing. slide the cotton in, cut the tails approximately, a little longer than needed.
Gently press the tails into a tube. Push them down the chimney.
Hey presto, a great vape!
Thanks again to all who gave advise.
