Back on topic, just one suggestion.....
Getting into building your own coils is certainly something to work towards. But try to find a set-up using a simple tank with factory coils and a juice that satisfies you first. Then you will have something working "well" to hit on while learning and fiddling with your builds. And back-ups are a very good thing! Desperate for a satisfying hit while building, not so much.
Consider a mod like the suggested Alien (+1 on the kit with BB) with all its abilities. You can always crank it down as low as 6 watts (I think) to fire any atty you have, yet gives you all the room you need to grow with your builds when the time comes.
Good luck! You can do this! And welcome to the rabbit hole!
