With what you have, you should be able to find close to your ideal vape. It's more a matter of tweaking the juice, power, wicking and wire. I have a bunch of different mechs and atties but I found how I like them set up a over two years ago. They are essentially all vaping the same so I can grab any one of them and get the vape I want.
What is it you are looking for in a vape that those aren't providing?
