I have seen a lot of gunked up coils and wicks on this thread. More than anything I would venture that the
juice is mostly to blame. I used to use a lot of NET tobacco juices of a high quality that had a 50/50 mix. Coils and wicks would get coated with gunk daily but I wanted that flavor to get me off tobacco. That was 2½ years ago. Now I make my own spice Horchata
juice that is very satisfying and only costs pennies to fill my Taifuns. I mix max VG (flavorings use PG as a base) and use flavorings from Flavour-Arts and other tested clean manufacturers.
For coils I use Titanium @26 gauge anywhere from 3mm to 2.5mm at 40 watts. Easy to clean, responsive and strong. I use Japanese cotton and pack the coils firm. On my authentic GTII I pull the wick past the bushing and prime. When I get the top of the chamber cap screwed on I spread the end of the wick in all directions. This makes a funnel shape and covers any gaps where juice might flow freely into the chamber and cause flooding. My authentic GSL is a more open draw and incredible flavor!
To power up these two tanks I use the Vapor Flask 2.1 with temp control "off" at 35-40 watts. I pay little attention to ohms but rather size of coil. My "go to" mod is the Dicodes No.6 because it delivers power to the Taifuns extremely smoothly. The "Ti" temp control set to 420-480deg. I use the Vapor Flasks out in the field mostly.
Both Taifuns are super stable in temp control and very versatile as far as tailoring your draw.
The juice I make has the best flavor at higher temps. Extremely high quality and much, much cheaper.
I only change wicks and clean coils every few days or when flavor is muted.
The money I save on juice let's me buy authentic RTA's from Europe and great mods.
My other and possibly favorite tank is the Vapor Giant mini 2.5 with the "Wide Open Draw Kit" installed. I have this tank down so well I don't even close the juice control when refilling (top fill). No leaks!
