What is the best way to build in an RDA? Currently I am using a single cotton microcoil in an IGO-W, currently I thread cotton through and then fill the whole deck up with cotton, is this what I should do, or less cotton?
How much cotton should you use?
Which is best, putting the cotton through the coil or wrapping it around the outside?
How many wraps for the microcoil?
Any other advice?
