Been at this for a while and I constantly change what I use for a backup. Currently I use a Stingray clone with a drop top KFL with a VCT5 inside(.5 ohms). My backup is my trusty old Kicked Atom clone in 18500 with a IBtanked carto setup on top. I have never had issues with the stingray setup but there is always faith in regulation and not having to worry(too much) about a carto failing.
