yeah i dont see why those premade coils wouldnt be a good place to start. in the long run itll be more expensive than building, but we arent talking a lot of money here. at least to try it. and the rafale x is a great choice. its my go to for sure. when i realized that the neutral post could be removed i had to try it. ive got two of them and love them. its a very high quality and well designed authentic RDA for around $20. thats a no brainer. esp one with the amount of build space it provides.
