An option to consider IMO would be something like the Horizontech Falcon sub-ohm tank with the M1 mesh coils, and a reasonable quality dual 18650 battery mod to go with that. The M1 coils contain 30% wood pulp so you don't have to wait as long between consecutive drags to prevent getting dry hits, when compared to using other types of drop-in (i.e., factory premade) coils. One of the downsides is that you need to "prime" your new coil, after which it takes 10 minutes of patience before you can start vaping on it but, on the plus side, it's really easy to do, and the coil should last a really very long time after that, giving you a pretty huge flavor upgrade over the setup that you currently are using. But another downside IME is that flavor can, and does, get even much better if you are willing to get and learn how to properly use a good quality RBA (i.e., rebuildable atomizer) with (a) good quality coil(s) that just about any person can learn to build, with a bit of patience and a basic set of tools and building materials. As for the size and portability, that might be yet another downside if you prefer to keep it really small. Pod systems tend to fit in that category better, so... if that's how you want to vape, then the Lost Vape Orion DNA Go is what I'll recommend for flavor despite its fairly high price tag (that is, for a pod system). But I probably should add that, to a lot of people, size and portability don't always matter all day long. So if that's your case, then you might want to consider going for both of the aforementioned options/choices excepting of course if you don't like to sub-ohm because, after all, vaping preferences are subjective. (All I'm saying is, you could decide to sub-ohm during those moments when your choice of vaping style isn't limited by the size and portability factor nor is limited by the social acceptance of producing a bigger cloud factor, and then just live through the gaps in between by using the Orion DNA Go pod system.)
