I am lost here too. Worst case scenario, we're talking maybe 1 drop of of eliquid? I never looked at tight wicking as jamming an entire cotton ball into the top cap....now, that would waste juice.Yep. I can pretty much guarantee I wouldn't like any of the atties he does, 'cause my vaping style is completely different.
But that doesn't mean his experiments aren't interesting.
I've always had better results with tight wicking than loose, even in the pre-historic past when I was using cotton instead of the rayon I've been using for just about 4 years now.
Can you explain why you think tight wicking "means wasting" liquid?
