I have also just recently got a velocity and tried a bunch of builds all coming out between .3-4, best build so far has been dual claptons 26ga wrapped in 32 on 3mm i.d at .35 ohms. I couldn't really notice too much difference at all between twisted, parallel and standard 26ga builds. Velocity is definitely a great RDA to get started on, building is super easy, i'm sure you will have alot of fun with it.
