Well, I guess the thoughts on exotic builds is they have more mass and more surface area to generate vape. Depending on your resistance needs and a dual coil as well, you may find you do well with simple round wire, or if exotic maybe keeping wire mass on the lower side MAY be helpful since you'll have a dual coil in any case, so you'll either have pretty low resistance anyway, and/or mass in your build since you'll have dual coils.
I'm not saying don't try exotic builds, by all means do try them, it's just that you are going to have to experiment with what works, for you, and etc. I ordered some higher resistance exotic coils to see how I like them (for little financial risk) and it will be interesting to see, so far I've only used plain round wire builds (I am however, a MTL vaper, so my resistance needs are probably totally different.) If I wind up enjoying some exotic builds, fantastic, and if I don't, well, at least I've experimented with some things.
Best of luck, and I hope you find the flavor place for *you* however you wind up getting there.
