I was just wondering, I hear ppl speaking of Soft top cartos. I saw one the other day at a shop and deff would leak all over the place in my daily routine. Are there hard tops that are maybe a bit more sealed??? Would love to be able to load up that much juice and still not worry about leaking like just about every tank unit ive seen. Also, Ive read you can use duel coil cartos w/ the ego cone. Will most other types of cartos not work with my ego cone atty cover?

Super glad I found this tutorial!! TONS of help!
