A 510 threaded carto should work on either of those
batteries. As far as suggesting a specific kind, there are almost too many varieties to choose from, I would say to experiment with a few different things if you feel up to it. As for me and my house? I use a 2.0 ohm single coil cartomizer in a
tank on my spinner, and it works beautifully for my tastes. My wife uses a 1.5 ohm single coil, also in a
tank, on her regular Ego style battery, and she likes it as well. Note, however, that dropping much below 2.0 ohms will limit your spinner. As far as I know they have a 2.5 amp switch that will get tripped when using the higher voltage ranges on low resistance cartos. Hope this helps a little bit, I'm sure someone more knowledgable than me will be along shortly to help!
