I've never tried aliens, but my go-to coils are simple fused claptons, dual core, 2x28g wrapped in 38g or 40g.
Is there really a noticeable difference between fused claptons and alien claptons? Besides the visual effect, I can't imagine that it would make much difference with flavor or vapor.
I'm always using SS316L for everything because TC is a must for me. Kanthal and Nichrome always leave me a bit of a metallic taste, which I never have with stainless.
