The gauge of wire, really depends on your taste, if you like lower resistance than you would want a bigger wire - lower gauge, if higher resistance then higher gauge, on average my coils I make with 32 gauge kanthal and cotton end up around 2.3-2.6 ohm resistance. I prefer cotton as to me it makes the vapor a little thicker and creamier IMO. really the best is to just play around with some different wick sizes and materials till you find what you like. If using silica wicks I tend to like using multiple smaller wicks than one big one. I mainly use 1mm or smaller, .8mm and then uselike 3-4 strands to make them. Another trick is to use something like toothpick of paper clip to wrap your coils. I use a straightened paper clip on mine, you just place you wicks on the paperclip or whatever you choose and wrap a good 4-6 coils fairly tight. Cotton expands a little more so I wrap those looser than norm. Good luck and if the first one doesnt work right try and try til you figure out what works for you.
If it is burnt tasting - coils too tight
If it doesnt really do anything or just a dry hit -> too loose
Be careful when cutting slit like in the vid above, it is a really small slit, otherwise it will flood.
But other than that practice, practice, practice.
