Right now the setup I have is an iTaste SVD which maxes out at 15 watts and a mega bcc tank. The tank is alright but it's kinda unreliable sometimes I'll get decent vapor and flavor others almost none and sometimes in the middle. I know its not a problem with the coil because Ive replaced it several times and it doesn't change the situation. I really want a new clearomizer that has good vapor production (big clouds if possible) and decent flavor... Any suggestions?
