i really really dont like the taste of cotton, its too much for me, i prefer the silica.
once i get some 28G ill build a 2mm ID micro coil and use some or other tool to loop 3 strands of silica through it.
edit:
but that being said this franken coil is doing the job for now....not a bad vape at all
Must be something odd with my tastebuds, because I have tried both many times. And I can't really tell the difference between the two. I just prefer cotton because it's easier to wick with a micro coil.
