I absolutely love my igo l on the nemesis, I usually vape a twisted 28 gauge coil, 2mm id and 5 wraps, comes to 0.5 ohms, cotton Wic and payow! Also drilled the igo l's air hole out to 2mm, makes a massive difference. This is currently my vaping navada. Very close, 2nd best for me is the Kayfun light, drilled air hole to 2.5mm and the same coil.Roger that... not very elegant but will certainly give it a go... I'm after the perfect Vape and the micro coil with cotton on the REO is pretty close... will try the Silica tomorrow! Thanks @devdev
