Having some technical issues here. I usually run around 0.20 ohm dual or quad coils, have been for months, but I've been building on and have become accustomed to a 14mm rda. Moving up to a 22mm is proving difficult. For those who super sub on a W, where do you put your coils in relation to the air holes and how big are your air holes? How much cotton do you use? The vapor production as of right now is decent, but the hit is harsh as hell. Not hot; just harsh. I vape 90/10 DIY with 1mg nic.
