Man if it ain't a tube mod, I'm usually using a two battery mod or something. Variety.
As far as a smaller mod if you want TC I keep hearing about the Jac-B but has to be ordered from Britain. If you want VW only, I'd say one of the Innoken models with a larger internal battery. I have a zelos mod that I'm fond of but it is internal battery only. So it kind of depends which direction you want to go in, honestly. The pico is always suggested so I'll mention it here, although to be honest I wasn't thrilled with mine, it was okay though... IDK.
