Did you make any progress with this? I'm in a similar boat - flavour not as good as the serpent mini and have tried a few different builds to try and "crack it". Certainly isnt living up to its incredible reviews so far...
Yeah used some different coils, and wicked as the video above. My blue slush isn't amazing in it, but my lemonade stuff compared to my 120 is incredible! I put the coil lower on this build too.
