hey guys as you know I am constantly doing different configurations for my k-lite, the latest one is amazing, although I am still fine tuning it. it is similar to my double vertical coil I use but this only has one vertical coil and is placed directly over the air hole. with this coil you cannot wick through it because it would block air flow, instead the cotton is wrapped around the coil. I remember gdeal did one with a custom ceramic wick in the k-lite and looked interesting so tried it with a regular micro coil. it really is just like a carto configuration where the coil is in the cotton. the difference in this set-up is the air flow comes right up through the coil, and this is producing the most vapor out of the k-lite then any other coil I have done with equal flavor too. I just have to fine tune the way in which the cotton is wrapped around it with the tails down to the channels. I have done it fairly good for now, but it needs some improvement because I cannot chain vape it right now but maybe after a slight break in I will.
