I use a regular 510 atty, you shouldn't need a HV atty, just use a regular 801 atty and drip for best results with your setup. Just make sure you keep it plenty wet. If using a new atty, blow it out first, then put 5 drops in it, if you get a burnt taste add 3 more drops. I usually add 3 drops at a time vape it til I get an off taste, then add 3 more.
