honestly ive read up on rdas and id love to try one out any that you would recommend?
You need to consider there are plenty of those.
Firstly, i need to know your vaping style: DL (direct to lungs like in hookah) or MTL (mouth to lungs like in cigarette). Based on your RTA, i would suggest you use a DL one
Second, we will pick your diameter. If you use Alien 220W (as far as i know) 24 mm will sit there perfectly.
Next, we need to fing whether you want to have better flavour or versitility. If you`re an everyday vaper (as i am), i`d go for versitility and check out side airflow RDA
4. Do you like warm/hot vape? If you like one, surely go for two-post deck (where you can put two coils: Velocity (old but gold), csmnt) but if not you should consider one-post RDA (Aeronaut, Vendy Vape Pulse, Vandy Vape Govad, also there are plenty or drippers that allow you to decide whether you want dual or single coil setup. Some of them: Twisted Messes, Goon (1 or 1.5. I dont really like LP - it`s not versatile at all - so it`s not a first-time dripper), Apocalypse, Skill, UD Skywalker, Druga RDA, Mad Dog)
Do not forget also there are clones and original devices
So Tl; Dr one solution:
Aeronaut, Vendy Vape Pulse, Vandy Vape Govad - 1 coil (can take both originals and clones)
Twisted Messes, Goon (1 or 1.5. I dont really like LP - it`s not versatile at all - so it`s not a first-time dripper), Apocalypse (better clone - too big of a price), Skill, UD Skywalker, Druga RDA, Mad Dog - either 2 coils or with possibility to place one coil)
