My first year, was a spinner battery and the Aspire ET-S. Not much flavor or vapor, but it worked, and I was blissfully under-aware of other options.
Then I broke both my little tanks in a single week, and got a mini Nautilus. I don't know if it was the Nautilus that made the difference, or if it was having a new spinner battery that hadn't been charged twice a day for 13-14 months, but I actually had vapor and flavor for the first time.
I'm still, I think, in transition. I have Lemo (v1), because I decided I hated buying coils, and it's sitting on an iStick 30W, which looks a little silly. I couldn't exactly sub-ohm on an iStick 30W anyway, but I think I've figured out that 1-1.2 ohms is about where I'm happy, and I've dialed back my Lemo to something closer to the way the Nautilus vaped.
I'm starting to look at another battery, something with replaceable batteries, but another RTA or two, and I think I'm set.
