Regardless of where I am, I am almost always using a KGO battery, (sometimes a Firefly battery), wearing either an eGo Stardust 2.1-2.4Ω, a Boge 2.0Ω, a Resurrector 1.7Ω, an EMDCC 1.6Ω, a CE2 2.6Ω, or a CDC XL 1.5Ω.
The cartomizer varies with the juice that I am using, (I find various juices taste better in certain cartomizers), and I may have 4 or 5 different types of cartomizers, all loaded with a different flavor of juice in my little Altoids box traveling with me in my pocket wherever I may go... my husband finds it a bit, um, excessive.
