Spaced or Touching single coil using Kanthal wire (non-sub ohm) ?

Sorry, I do know you know your stuff, but I haven't stated anything of the sort you're mentioning and fully agree with you

No problem. I doubt, I know anything more than you. Sometime I will say thing just to clarify what my impressions are.
What I do know is what my vape experience is. Understand, I vape mechanically. So at a given ohm with a given wire, the power is always the same. I know what my vape results tend to be. I know that if I set up 2 Kayfuns with the same Coil (wire and ohm). and do 1 as contact and the other as spaced. The contact coil will vape the juice faster and burn more wicks and gunk up faster. I also think I get more vapor and flavor from the spaced coils and only burn a wick when the tank is dry. This, has to be because the heat is spread over a greater area of wick. More wick means more juice available to the coil to be converted to vapor. This can result in less perceived heat, I guess. I does make sense that a spaced coil would be more affected by the cooling affect of airflow and that extra juice. But the fact remains that the heat and power at the coil are actually the same.

Spaced or contact has no effect on surface area. Juice only vaporizes where coil contacts wick. I'm pretty sure these are facts. The only difference I've noticed is my gunkier juices can go a little further (maybe 10-15%) between rewicking on a spaced coil with the same properties as a contact in the same tank. The spaces of wick between the wraps of the coil are not getting hot enough to vaporize liquid, so the theory of spreading the heat out doesn't make sense to me. Like I stated, the juice is only vaporizing where hot coil contacts wet wick. I believe the less gunk effect is just a matter of perception, as it is just less localized when spaced out, versus compacted when in contact. I've noticed less discoloring on the wick tails since I returned to contact from spaced coils, though the coil tends to appear darker and gunkier sooner... the flavor never seems to get any worse. The contact coils are also much easier to wipe with a moist qtip when warm to clean the gunk off which allows me more time between wick changes.

93gc40, Cool, I agree with you fully I have same experience as you and btw, i'm waiting for my first 2 mechs and looks forward to changing to them(smpl+nikita)... On regulated devices I always leave them at 4.2v and use my builds to tailor the output instead of the device...

daveid777, You're right, sorry! It was a big strecth, and it was something I read some time ago and thought maybe it's was correct...

Yes the surface area of the coil is the same.. But if you spread that coil over a bigger area you have more juice available at 1 time to vape from. Stainless wicks are a good way to see this in action. With stainless you get many more hot hits from a contact coil vs a spaced coil.
