For the best hit I have gotten, it is using an 18xxx series device like the Provari, Precise Plus, Legacy, etc., with BE112 HR 'Pennstyle' atomizers at 6.0 volts on the Provari or 8-9 watts on the Kick, with a 'fire and ice' mix at the 24mg/L nicotine. The fire and ice mix is usually a menthol and cinnamon mix, and it hits hard. I've also read that the Darwin is a must have for those who cannot get enough.
