I also have a Nautilus 3, and it’s quite good.
Basically, I always used MTL too, but I’ve switched recently. Vaporesso (and others too) have atomizers that are transitional between MTL and DL. The GTI and the GTX (the ‘x’ ones are mainly designed for Vaporesso mods named ‘x’)
Most of these (almost all) are sub-ohm, but those above 0.4 are more MTL-oriented. Those can rather be used this way.
Very durable atomizers, sometimes they last more than a month (for me), of course, they consume liquid more heavily. And they give very good flavor and vapor.
I use these atomizers with a Vaporesso XR Max Lux mod, but there is also a tank with a standard 500 connection for GTI and GTX atomizers. Just recently one of the Chinese (perhaps one of the oldest) websites had them on sale, so I ordered both tanks, when they arrive (the journey is long…) and I try them out, I will report back.
I don’t know if I can write the website address here, but I will send it if you are interested, although maybe you already know it, someone here also drew my attention to it. They give quite a lot of discount on subsequent orders, and they are reliable (besides being cheap).
