Top three vape mods: Provaris, Steampunk Tesla Nano 120, and an aspire speeder. That's probably not much use to you and I MTL but I have used the Cleto Aspire sub0hm tank and it's topfill and leakproof and pretty cloudy, comes with 0.15 coils. I liked the tank, I just don't like to sub0hm a lot, but I do recommend it as a sub0hm tank, easy going and decent flavor.
Good luck, I am sure you will get more (and better) recommendations than mine. The cleto is quite nice, though, and you can get a 5 ml extender tank.
