This is a slim 510? Or any slim model? If so, you should only be using standard resistance atomizers - like things 2.5 to 3 ohms single coils. That may eliminate many of the things that were linked or suggested.
In addition, if you have auto batteries, dripping is never recommended for auto batteries. But it's fine on a sealed manual.
Re 901 - I did not like them for dripping - they have a hole in the sidewall for airflow and liquid will drip out the hole onto your fingers or clothing. Also I had trouble with the barrel rotating relative to the brass threads and that caused some kind of plastic or nylon brace inside the coil compartment to partially block the air intake hole. I also found them difficult to keep clean since there it was mostly sealed below the coil compartment - made it impossible to flow water or alcohol through the atomizer. Brand 901 - 901 was very nice for dripping (other than the leaking) but they went downhill fast IMO. If all of my batteries were 901/KR8 threaded I might use 901 attys to drip for testing liquids, otherwise no.
