Farawayinn, I would suggest to go for the easiest set up. Cutlass DNA20 / A7 or Cyclone atomiser with some nice wick. IMO you can't go wrong with a bottom feeder, you have all the advantages of dripping, without the negatives of having to carry a bottle of liquid in your pockets. The DNA20 is easy to use as well, it does all the work for you, set it up to what you like, forget it.
As for the atomisers, A7 is quite cheap, and works well, I still prefer the Cyclone though, but that's only because I'm still not too good with airholes on the 510 connector I guess.
If that is you're very first bottom feeder, I would even suggest that you use a regular 510 or 306 atomiser for a while (Ciscos for example). That would make the learning a lot easier if you learn how to feed and the kind of pressure you should apply if you can actually see the liquid. Once you're comfortable with that, you'll naturally move to blind squonk, and know when to feed without even thinking about it. Once you're good with that (should take about a week), move on and grab yourself a nice RBA.
If you go for the Cutlass, you'll love this thing so much you'll never go back to anything else. The kind of device that actually lets you VAPE instead of spending the whole day trying to make it work well.
