That’s a pretty deep rabbit hole you’re flirting with, watch out. I’ve never bought premade and packaged coils...I’ve made all mine by hand (and drill, of course)..not so much as a Clapton has made its way into any of my RDA’s that I didn’t make. It can be frustrating at first, but once you find your “Ah ha!” moment when everything clicks and syncs together when making your own, you’ll never go back...consider yourself warned, but if you fall in, no worries, there’s a thread here with just as many people offering advice and help in the “Post Your Build” thread that there are here for DIY stuff.
If you do fall in, welcome to the dark side
As for mixing, I kept it simple and straight forward...didn’t feel like mixing something new and run the chance of it not working out, so, just made a Time Bomb Clone from TNT
You’re not drinking water are you? You realize that’s an ingredient in antifreeze!
