Sorry it was clippinwings that said that. So I'll explain: It's quite common to build a subohm coil that runs as cool or cooler than a consumer coil. That's how subohm works after all, it's not like suddenly you are vaping at a super high temperature. The juice still vaporizes at the same temperature. You are building a larger coil which takes more power to operate.
The size of the coil sets the size of the vaporization zone and therefore the amount of juice you can vaporize at once, this is why large coils produce more vapor than small coils. However the temperature of the coil during operation runs in the same range as any other atomizer.
Your juice would probably taste fine in clippinwings' subohm coil that runs cool. In subohm atomizers that run hot, or when you hold down a button for a long time, you soak heat into the coil and surrounding parts of the atomizer, which affects the wicking of the juice in the area of the coil on continued/subsequent firing as well as affecting the juice itself (reduced viscosity, possible boil-off of volatile compounds in surrounding juice, etc.)
The way to tune this would be to build differently (e.g. increase coil mass) or to feather the button in operation (remembering that wattage figures are instantaneous figures, time is a factor in total energy to the coil/atomizer).
So yeah. A lot to understand, and I don't think many people have put all of this together.
