I have one of the original Picos, won it here in some contest back in 2017, but I've RARELY used it, for a couple of reasons: 1) it's just too damn small for my hands, and 2) that top batt-cap is infuriating, you can't get your fingers on it enough to open it if the atty is attached, and that's a huge pain in the ass, since I use the same atty all the time -- I very often have to change the battery while the atty is attached, and though I do have to loosen the atty a bit with the Minibooks, to get the battery in without nicking the wrap, I don't have to completely remove it. Those newer Picos look to have exactly the same two problems. The Colossals look to be just about the size I like best -- fairly tall, but not terribly fat -- much like the Minibooks and CF4s.
I don't have any 2x700 batteries or mods. The only variation in batteries I have are the 2 Aegis mods, and I did get a couple 28650s for those, and I'm pretty happy with both those mods, and the 28650 batteries, since they last about the same nearly-3-full-days as my 30Q's. If I was going to splurge on a 2-batt mod, I daresay I'd probably get the Aegis Legend; my son has one, and he's been very happy with it... and it's apparently just as klutz-proof as the original Aegis.
But with my extremely low-watt vaping, I just don't really need a 2 batt mod. My hope is that with the newer sizes of batteries, and the 2-batt mods, there are maybe lower prices now on some of the better single-18650 mods.
@nadalama, what do you dislike about the Puxos? That's within my price range and in-stock at MVS, one of my preferred vendors, and I really like the looks of both the P2 and P3... but I've never had an Aspire mod, so I know very little about 'em -- is there a problem with the Puxos? Apparently it does come with an adapter for an 18650. I like the size/shape of it, along with the looks of the P2 and P3.
You're right, I really don't want any of the "starter kit" things, that come with attys; I can't use any of the newfangled attys, and my son is stuck fast to the mesh one that came with his Aegis Legend, so he probably wouldn't want it either. I need to get him another of those mesh attys; he broke the "bubble" glass tank on one of his, so he started using the one I gave him for xmas... so heaven help us if he manages to break THAT one.
