Eleaf makes a good tank, imo. Melo 3 has 2 sizes, the regular size is 4ml and the mini holds around 2.5 ish ml. Both use the same coils and altho the factory recommends a higher wattage you don't need to go that high. ie. I use a 0.3 coil and like the watts around 10-15(depends on the juice) Nice mtl vape with loads of vapor.
And both sizes fit on the pico.
Eleaf also makes the same coil in a rebuildable called ECR. Super easy to recoil and wick and then you can pick whatever wire you wish to use.
I really think you both will like this setup.
