I started at 24mg with an eGo-T kit. This worked for a couple weeks till I switched from the atty heads to cartos, with cartos I bumped it up to a mix of 36 and 24 throughout the day. I switched to a Genesis device (Z-Atty-Pro) and the 36 damn near blew the back of my skull against the wall, moved back to the 24mg for awhile.
I'm now at 18mg and happy there, 12 is too light, 24 takes my breath away, 18 is juuuuuuuust right.
Oh and Juggy's KaramelAPPLE is my ADV... MMMMMMM FREAKIN DELICIOUS!
