I pretty much only use TC with my subtank... I have wicking issues with it that I never was able to fully overcome. On my 90 mile drive to work dripping a a nuisance. Now with a .08ohm 28 TC coil in the
tank I set the temp to 400 and Joules to 25 and
vape the entire drive. Once at work I normally toss one of my kanthal coiled drippers on for the day, and then toss the sub
tank back on for the drive home.
