Mini Protank 2 and EVODs are great for true pocket vapes. Run all day on a tiny 650 mA battery too. Watch out for Protank 3 and EVOD 2, much more common now, perhaps a "cleaner" vape than the single coils but often less flavor, even with more juice and battery consumption. These all will require a recalibration of your technique after using larger devices however.
PT coils are made by the manufacturer using welded nonresistance-resistance-nonresistance wire assemblies. While many have made coils with regular wire, I'm still skeptical about the reliability and safety of doing so. You can get pre-welded coils from fasttech for cheap but the wire combinations aren't quite ideal. I'm using the 34 ga. 2.4 ohm because I couldn't get low enough battery voltage for the 1.5 ohm 32 ga.
