I have a ton of dvarves v2, bsrk 1 and 1.5( love them), all of them 2mm ID ,28awg 6/7wraps, and ALL of them on the smallest AF, 0.8mm/1mm on bsrk 1.5 ( which is like 0.8 on v1 if you're lucky.Tight.).

I am constantly bombarded how fev or spica are far better for TH and flavor.

That so? Care to enlighten a fellow vaper ( looking at you, maestro Essellar :) i know you like to vape ~0.8-1mm AF )
