Oh, I'm sorry, I missed the second part of your question. I use nic salts exclusively ATM (I DIY though). I mainly use them for the lack of throat hit (can use higher amounts without harshness) as my throat was torn up when I got here. There are some reports they are bioavailable faster, can't say I've noticed a huge difference there, but I DIY like I did freebase nic, at 18 mg/ml.
You can use nic salts in any device at the correct percentage for your device, but they tend to have more "use" in high mg solutions, as you can go higher without harshness. I think the Juul tops them all with a "proprietary" 50 mg/ml nic salt pod (but you have to keep in mind the puniness of the delivery system, I mean, the Juul is weak. Although if I had to only vape a cigalike, it might just be the Juul.
If you are interested in exploring more mouth to lung setups, there are some decent options (and since it's all 510 connections, for the most part, you don't need a new mod, you can just run a tan on your more powerful mod at lower wattages and get great battery life.
MTL tanks: Um, the Nautilus 2 is well known and well liked for the most part. This was my quitting tank (fair disclosure, I no longer use it, I've moved on to MTL tanks and setups that are better in terms of capacity and flavor, although the nautilus COIL can be accepted by many tanks and I still use some of those tanks (mainly the Kabuki. It's pricy. I used to recommend clones from Fasttech, to sort of "try out" the tank, and get used to its foibles. I kind of no longer do, as I don't consider the flavor remotely comparable, although it's a bit of a finicky tank for such a high price tag, it's bottom fill and fairly "easy" bottom fill, once it's broken in. It's a great tank though, I own two of them (and they aren't cheap) but probably the best flavor you'll get out of a nautilus coil.
The Ijoy elf is kind of ignored a lot, it does come with proprietary coils and it will also "accept" nautilus coils and pretty much fixes all the N2 "problems" true 2 ml capacity instead of 1.7 if using the fill line, easier to fill, a much easier top fill, and there's a metal cage but it doesn't heat up as fast, etc.
The Ego Mega One V2 tanks are great, some of my favorite tanks. You can get 4 ml capacity although it's bottom fill it's not a "terribly hard" bottom fill. The Tron-S is similar in capacity (ugly as sin in my opinion though I own a couple). The magic in these tanks is in the coil, the Joytech CLR coil comes in 10 resistance and 0.5, you might well enjoy the 0.5 coming from sub0hm although I LOVE the 1.0 resistance. Great flavor and the coil can be rewicked or even rebuilt pretty easily. So, those might be an option, I want to say the 0.5 is a TC coil only, but I could be wrong on that, but I'd check to make sure because for some reason I am thinking it's titanium, I could be wrong though .I'd check.
Okay, hopefully some of the above was useful. Best of luck,
