I like the air flow (3mm wick, afc wide open)
though I have to say I liked the 2.5mm set-up
but I just wanted more Cotton inside...
when I fool with the 'gold pin' (3.5mm + insert)
I need to close it off some
the 3.5mm alone is to much for my liking...
Isn't it Amazing how one can Fine Tune their Hit when they Build their Own coils?
