After everything I've read, handling anything over 60 would make me nervous. I'm just not gonna wear rubber gloves to mix nic... seems to me the gloves would make me even more fumble-fingered and likely to spill something.
My first two nic base orders were 48mg, still have over half of the second one left. On my last order, to stock up in case of vapocalypse, I wanted to get 100 and immediately cut it in half but chickened out and just got 60. I wanted this bottle for long term storage, and didn't like the idea of breaking the seal right away.
Andria, I have the same problem with my wife's VV3 when using T3S's on it, sometimes no contact... easy fix though.
Straighten one leg of a large paper clip (small ones are too flimsy for this), take clearo off VV3 and stick paper clip end into the little hole in the bottom of the coil head.... NOT TOO FAR, just a 1/4" or so. Push it sideways and wiggle while pulling outwards on the clip. This pulls the center pin out just enough to make good contact.
Good luck with that combo, it's a good one (well, except for the occasional "no contact" issue). My wife loves hers, and hasn't smoked even one Slim since... going on a month now.
