I had a bit of time to kill so I built my first vertical coil on my Subtank Mini RBA... WOW! What a huge difference! Flavour is incredible and vapour production is massive! 6/7 wrap with 24g kanthal at .5ohm. Once you go vertical you never go back
off topic... anyone else enjoying a slightly cooler vape at the moment with this hot summer? Dropped down from 45w to 24w
