Oh and no I was not aware of this at all twgbonehead. Thanks for bringing that info around my way thoughNow I'm actually kinda keen to jump onto mods..
ih8,
Start by looking at "regulated mods". Something like the Innokin MVP20 or the eleaf istick. (Perhaps these should be called "PV's").
I'm pretty sure that with the kind of head you are using, these are a much better choice than a "mech mod" (battery in a tube with a switch). I have the MVP V2 (the 11-watt version) as well as the istick. Both great, with different advantages and drawbacks, but I would recommend either as a great choice. Either of these will take the head you're currently using, as they are ego/510 threaded (which means they take either one).
The head you are using is ego-threaded. This means that the battery has threads on the outside, the head has the threads on the inside. If you find something that is only 510-threaded, you can use something like this to turn it into ego threads:
$3.38 510 to eGo Adapters for E-Cigarette (5-Pack) 5-pack at FastTech - Worldwide Free Shipping
(with 510, the battery is threaded on the inside, mating with a head that's threaded on the outside).
