Well, I have and use all of those tanks. I started vaping a few years ago on Kayfuns and use only single coil rebuildables now, so I have a fair amount of experience. My preference is restricted lung hit, so I will share what I have found to work best for me. I get the best flavor from all of my tanks when I fill the interior with the largest diameter that makes sense, usually 3.5-4 mm and however many wraps it takes to fit between mounting points, usually 5-7. I have several different spools of pre-made s.s. In various varieties I play with, I'm liking an alien right now. I wick with Rayon, super tight in the coil but trimmed down as much as you can get away with as to not leak. I really like all of the Serpents, especially the RDTA, but they're all really good tanks. The new SMM looks really promising also. The Merlin mini doesn't get used as much. Good flavor but it's janky juice flow control bothers me, it always seems a little wet, there's a lot of parts and it's thirsty.
