I feel this needs to be clarified before giving advice. Personally I'm mainly a DL vaper, The flip side of that is MTL.
Mouth to Lung (MTL) is where you suck into your mouth then inhale that, it replicates how most people smoke (personally I guess I was doing it wrong
)
Direct Lung (DL ) is where you just breath it right in. This is what you do when you go for clouds.
There are devices aimed at each group. The Nautilus which is a great suggestion for beginners is more a MTL tank. The reason I want to clarify is because I started with MTL tanks direct inhaling, and with that I kept buying new stuff every month. At this point I have a giant collection, given away most of my early stuff but I still have my starting DL devices stuffed in a drawer. So if the DL type vaping sounds like more your thing you might not be satisfied with the pen style things or the Nautilus and end up scrounging together some money and buying something new in not too long.
So just something to think about. As far as juices, I use some that's very well priced (like insanely good prices) but I wouldn't recommend it to a MTL style as it's a more subtle flavor and you could likely find something more your taste. What I keep well stocked in Verdevalleyvapes, but there are much better juices for MTL, things that have a much richer flavor.
Anyways, if you have any thoughts on that I'll try and get back with some suggestions on DL options if that's the way you go, if not I'd bow to much more knowledgeable people on MTL (I just dabble, I only really do it in certain situations like going to a bar or party).
