If you don't mind 510 drip tips: Super Tank Mini 510 Drip Tip Adapter
or silver: Tobeco Mini Super Tank Sub-Ohm Tank 25mm
I have found the vaporesso CCELL coils to work great in the 25mm SuperTanks: Vaporesso Ceramic cCell Coil
I haven't found a lot of difference between the 0.5 and 0.6 ohm coils but the flavor is great and they last me for about a month.
