Believe it or not, that's only a hotspot because the wick is acting as a heatsink for the rest of the Kanthal and drawing the heat away from it. So, you see it red there because there is no aluminum to act as a heatsink.
Because it is wicking heat away it means that the vapor that is produced does not taste in any way shape or form burnt, or like any "metal" so the flavor is probably the truest flavor I have EVER tasted in a genesis device. Smooth, not much kick (burn) good throat hit and once I dial in the coil where I want it, will be a veritable fog machine. Since it's pulling the heat away from the Kanthal, you could probably run those sub ohm coils without having to worry about burning that juice.
I currently am working on getting some beta testers for the wick and am sending them out a 2" section to test. Only requirements, having tried and used stainless mesh, rope and ceramic and have a 3mm hole in your genesis.
Oh and being willing to pay $2 shipping.
check, check, and check!
