I mainly use my Precise+18650 with a kick that has stayed @ 8.5 watts for quite a while now.
For the most part i have a DUD attached to it. That or my A7 repairable to sample or try out new flavours.
The A7 is meant for my REO Woodvil, which is currently being refinished.
I also have a Vivi-Nova with a few spare heads, for when i'm out of town and don't want to deal with shorts on my ss wicks....
I keep my coils to around 2.0-2.2ohms coil gauge varies(28,30,32) depending on how many wraps i want.
and I vape a 50/50 mix and stick to the 6-8mg stuff.
All my juices are ADV, i tend to stick with the sweet or minty flavours.
Very few tobacco flavours make it onto my shelf.
Also got a REDDS kit coming to me for discrete public use.
Back on topic!
the eVic.... i can see this as a good contender for those that want to get into the variable stuff, it's really just JoyeTech not wanting to feel left out.
their twist does a good enough job....
