Can not say anything about the KF
coils, but I would say the Taifun is an easy build.
The Taifun GT was my first and still my only
rta. My coil and wick building experience was with a Patriot clone before this. I nailed the first build of the GT first time using a 1.4 ohm coil with cotton. So new to me, I have only coiled it once but wicked it many times.
