I've got 6 mods that work. A Provari 2.5, an iStick TC60W, an iStick Pico 75, a Cold Steel 100, an Armor 'regulated mech', and a Sir Lancelot 'real mech'. My favorite of those is whichever one I'm using at the time. As for atty's, I've got a Gotank, a True, a doggie styled Doggie, 2 Serpents (a mini and a SMM), and a Brunhilde. I've got an Innokin X.I clearomizer too. They are all different in their own special ways, but my favorite is in the same category as my mods..
