There are a lot of options, I can only tell you what works for me: either an LR 510 atty (1.5 to 1.9 ohm) at 4.2v to 4.8v, or an SR atty (2 to 2.9 ohm) at 4.8v to 5.5v, or an SR+ atty (3 to 3.5 ohm) at 5.5 to 6 volts.
Use a solid 510-to-510 adapter (2 stacked sometimes) plus a dripshield. The bottom O-ring of the dripshield sits on the adapter, and the top O-ring at the top of the atty. Plus a driptip to suit yourself, my favourites are SS metal ones.
I add 2 bonuts to the inside of the atty as this allows them to hold more liquid and feed it smoother, IMO. In the old days we de-bridged and de-wicked atties as the
vape was a whisker too cool at 3.7 volts, there is no need to do this now as we have VV to heat it up.
This rig takes maybe 8 or 10 drops at a time, so it lasts well compared to a bare atty. If you get good quality 510 atties then there is probably no need to spend more on specialist ones, but that again is a matter of opinion. Everything in this game depends on getting qood-quality gear in any case. Even so I don't usually get any better than 3 or 4 good atties from a 5-pack. They last for months though as long as you rotate them
throughout the day, and if you don't clean them out viciously for new flavours all the time. There is no need to do dry burns or stuff if you do this, that's what shortens their life. Now we have good VV gear there is far less need to clean them, the higher voltage does that for you.
An alternative, if you prefer atties to cartos or clearos etc, is a BF boxmod or BF VV boxmod. This is probably the perfect atty set-up. For me the perfect rig is a VV feeder boxmod, it is atty heaven.
