So after maxing out my vaping on the ego stick batteries I upgraded to the itaste svd loved it looked beautiful work flawlessly then upgraded to the heimdall mechanical and it's oh lawdy so good but I'm still learning about it and I'm curious if anyone has any input on using the igo-L rba or the kanger aerotank (yes I know they are 2.0 ohm stock but I rebuilt it to .6ohm) still not getting as much vape as I would like out of either partially because I still get choked up a little but I think it might be my coils as well the igo l has 7 wraps of 24gauge kanthal works good but it's to hot and burns my mouth so my question is should put a dual coil on it or just change wire gauge and go with more surface area that way? Yes I have the proper batteries and chargers and al that good stuff any help is appreciated thanks to all who can help
