I in fact have a cuboid with a twisted messes rda. I love that combo. In the rda is dual 24/30 Clapton coils wrapped 5 times, inner diameter is 2.5mm. And I have the coils spaced. I run it in power mode at 90 watts. Mega flavour and cloud production. In fact I had to dumb down my juice with non flavoured VG because it was too much flavour. So much that I was getting a film inside my mouth afterwards. It starts to spit after 100 watts and at 80, it's good but it is not the sweet spot for the juice.
Yes everything depends on coils, juice, build, deck, mod, settings. This is what works for me.
