from my experience. more complicated builds do not help
i use simple SS claptons. i find them to be more flavorful then vertabraid (6 wires braided) and single wire coils
however i find the difference between a basic clapton and a fused clapton or alien to be so minimal its not worth it. Yes a well made alien has a bit more flavor then a simple clapton, but I can't even make a simple clapton so buying well made aliens is not my thing. I buy pre spooled clapton wire. Fused claptons taste identical to me as a simple clapton so why use the extra wire and lower my resistance even further
I think I prefer the clapton over a single wire coil mainly because of added surface area which to me is what increases flavor.
but all my rtas take 4mm ID coils so I can get a lot of wire in there and get plenty of surface area.
maybe at smalled IDs an alien or fused would have enough increased surface area over a simple clapton that I could notice more of a difference
I think there is a lot more to the right coil then just more complicated builds..
When I got my first rta and from then on, I put the biggest damn coil I can fit in it. my griffin 22ms have 316l 28/36 claptons at 4mm ID and 8-10 wraps usually. I dont care that the ohms read .7 or higher to start with and as the coils heat up it rises to 1.4+! I just feel to maximize the RTA or RDA you should fill it up with wire and that has worked for me. It May not work for anyone else in the world.
I just follow the theory to get flavor you need to vaporize juice, you do that with surface area of a coil. use the biggest coil you can and you cant get anymore surface area so that is as flavorful as you go on the atty.
and adding more cores doesnt necessarily increase surface are that much when you are putting the biggest coil you can in any way, because you wind up having less wraps and dropping ohms so much you might not even be able to use the coil on your mod.
I also think each person has a max amount of flavor they can taste.
so if coil A produces more flavor then coil B for Person 1. If the most flavor person 2 can taste is produce by coil B, then coil A is going to taste the same as Coil B
but since everything I ever read said flavor is about surface area, and I use the largest coils possible in my attys, I dont think there is much difference if any between simple claptons and anything more complicated
