I'm partial to the Sophia. I had a Gus Aiolos that I tried, it's like the Spheroid and I think the vape is comparable but the Sophia is so much easier to build, IMO.
My Microstick just got sent, the seller recommended the Doc Dave Mini Micro to go along with it, so thats coming in as well. I hope it fires
As a backup I ordered a couple of Aspire Mini Vivis, to use when trying to build my first, really liking these kind of mods, I cant stop eying a Kato but enough should be enough.
