Hello, jsmart506 . . . Welcome to ECF.
When I first started vaping, I used ego-c twists and everything, which you are currently using. Having noted that, I never experienced any leaking issues with any of the said delivery devices or the JC juice.
At the time, my only issue was that the JC juice was too thick, as it was 100% VG. Has JC changed their formula or have you diluted the juice?
