Properly built a Kayfun never needs Primer puffs. At least my 7 don't.

As for suggestion #2 - I use all wide bore short tips anyway so no gain.
Properly built being the key word here...and not just the coil/wick portion either
Love my Kayfuns and they all "hit" very nicely..however, occasionaly they might need a primer (almost all 9 of them

) - could be the channels are a little bit narrow, hair bit too much cotton, wick may be gunked up bit (especially with darker eliquids), seals need to be tightened..or..just not the best build on my part.. never a problem and I normally don't have to cover the airhole ..which I always remove the screw...
Agreed on number 2 as I use wide bores for everything now - drippers and tanks..
but what is the deal as I see more and more people using RDA's with no drip tip and they say te vapor and flavor is better ?? scares the crap out of me ..LOl
