Hehe what to say without adding to the confusion.
Definitely a hands on thing. It's easy to overthink it before just jumping in. As long as you use your provari or vamo, you shouldn't really have any issues with shorts. Hotspots is mainly a SS mesh thing. Even there, you won't really know until you simply fire it up. Hotspots might snap your coil, but they won't damage your battery. Coil will simply snap and there's no longer an electrical circuit to worry about. Just try again.
Also, with your totally fly abilities

you should have no problems working on any of the Kanger heads. Just pick one apart and/or watch a tutorial and you'll see theres really not an enormous potential for getting it wrong. Even if you did, your VV
mods don't fire them up if they're shorted.
I'm no expert. Neither do you have to be.
(Never tried the Terminator TT, but the Aga is a challenge at first. Just fail until you get it right.)
Can I ask... what what what why do people dissect fly maggot eyes? Really curious. Never heard of such a thing.
