I am looking to find a tank that will be good for my chick, it needs to to be 20mm max she does not like heavy or big tanks and she has 2 smaller sized mods so its gotta be 20mm..that being said I wanna be able to rebuild her coils, I build all my own coils so it sucks to have to dish out cash for her prebuilts. So if anyone knows of a good 20mm rba I would greatly appreciate the advice.... I'm sick of buying coils for her lol....
