Well...Mr Baditude !! It is like a reunion around here. Three of my very good ECF buddys !
The Kayfun is fantastic of course. The Taifun is a bit different...just a tad harder to place the coil on the thing (not a big deal)... easier to replace cotton and to fill.....the leak factor is better on the Taifun... (though with prctice not a problem with either)..... and the taste ? It may taste better than the Kayfun and it may not..... I like both....some think the Taifun is better for taste. The Kayfun at a 1.0 to 1.3 coil definately gives you a more powerfull hit/draw. You use much Less juice with a Taifun. It has a lighter draw than the Kayfun. (both of mine are wide open as possible..I like a big draw.)
I also enjoy a 1.0 to 1.2 ohm coil on both the Kayfun and Taifun.....I usually do 7 wraps on a 5/64 drill bit with 28 wire. (probably get better flavor out of a different guage that I could wrap more times)
By the way, plus one on the Kayfun has a better taste than a sub ohm set up.....my opinion as well.
