Welcome to the forum. The basic Micro coil works best in most applications. I have been building my own coils for 6 months and I still build one from time to time that looks a little boogered up. But as long as it works properly I'm satisfied. I also just recently quit heating and squeezing the coils unless it's needed. When I test fire them if they fire up smooth and even I leave them alone. Squeezing them will cause them to ramp up slower so I still use that in a dual coil build if one is heating up faster than the other. Otherwise as long a they glow from the inside out I leave them alone.
Good luck and happy vaping.
