Oh I DO love my big Chuck!! I just want to be able to go between 3.7 and 6 for some juices

I am strictly a carto user (stop giggling at me now!) so I don't have an assortment of LR, HR atties, etc. I use Boge 3+ohm in both 510 and kr8 cartos. I tried the GenJoye 510 and altho the function was good, the syringe filling isn't my thing.
I may grow up and graduate into atties and dripping some day but I'm comfortable with my carto training wheels for now
