i did do a few bng tattoos with the centri and loved it but some of my smaller mag tube have dings in em and they wont fit. (other people using them and cranking the shit down) so ive been mostly using it with disposable 15's. i havent had tons of luck with solid color with it running around 7v it seems like i have to go over it way to much(like 4 passes to get it solid). idk if its just me but my neo tat and coils seem more proper for packing one pass. i would definitley suggest picking up a centri though i did a few tattoos on my wife with it and they looked healed within a few days.
