I am eagerly awaiting the verdict(s), as I am also almost at my end - having the Sig, Picos (love the tanks, hate the stock coils, tried a 0.6 cCell, it was a rubbish one and I could not care to try again, the 0.9 ohm is lying unused on the Melo heap with the Kanger Subtanks, building the ECR heads is just too finicky, the hands and fingers are not as nimble anymore (and I am a portrait artist, so it's a bloody bummer in winter)).
I am in two minds about the Minikin or another Sig (Fuchai213 or 150w tc), or maybe just both. I need something that will last, easy to maintain, and am partial to good power management, and that can withstand my hectic outdoor life, and an Avo (or two).
Currently using Geekvape Eagle, love it for its capacity, Limitless Plus - fab flavour and enourmous tank, Theorem, Bellus - unbeatable for dessert flavours, Velocity RDA, Kanger Protank 4 as back-up.
So, all in all, waiting for my mind to make itself up
It'll be awhile before I decide as I'm in no hurry to work through the list. That is unless I find something I really like sooner, stop there and just buy more of them.
Like with everything else in vaping the gear is a personal thing. Matters not what anybody else likes, what you like best is the right gear.
So just my opinion based on my experiences... the Melo III/III Mini's were what I considered the best of all my ceramic coil tanks. I never used anything but the Vaporesso 0.9Ω cCells in them. All the other stock coils that came with them and all the Vaporesso tanks were just put aside. By far the worst ceramic coil tanks I bought were the two Cerabis tanks (and way too many coils for them). The ridiculous number of Vaporesso 0.9V coils I bought were also a waste of money if I never use any of the tanks that can run them again. The biggest piece of junk bought was the Theorem.
The Avo's are all dialed in and get it done in spades for me with the builds and liquids they run. I put the builds in them I knew would be spot on, easy wick them and use them with no fuss of muss for ages other than constantly refilling them when they are in my rotations. Not an issue, refill juice is always right at hand, only takes a few seconds and they are back online. But they have more than doubled the amount of juice I vape every day/night. Also not an issue as I DIY almost all of my own liquids. Getting back to some of my Reos more is what it's all about now days. The TC mods/tanks are mostly just something to play around with. I also need to step up my DIY as I want to come up with some new ADV's.
