I have to disagree about the power needed to to get good performance from the Crown coil's... In all fairness though, I can't speak about Nickel coils because I don't run TC even though I have a mod for it. The SS coils are 0.25, 0.50 and 1.20. The iStick 50 will work ok with 0.25 - that's a strong OK. Maybe not GREAT but pretty damn good. With the 0.50 coils you'll have no issues, and certainly not with the 1.2's
I like a cool/warm and also warm, even sometimes v.warm vape, but not hot and 80 Watts is a hot vape (OK, you might like it for the 0.25, or maybe not). You certainly don't need it for the higher resistance coils. Vaping360 is off-the-wall (yeah, I read it too), and I don't trust or believe everything I read. Maybe you shouldn't either. I'm just shootin' from my own experience fwiw.
