I actually ran into this. I just wasn't getting any flavor out of my ADV and I was using a protank. I mustive rebuilt about 30 coils. My ejuice was 100% VG, but the vapor just tasted bland and watery. Plenty thick, but no flavor. I chalked it up to vapors tounge, but for the heck of it, I rebuilt a vivi nova head, filled the tank and the flavor was back.
Now, I love the protanks, but for this particular juice I'm getting better flavor out of the vivi. I also tried it in a carto tank, and plenty of flavor again.
I did try rebuilding the protank with stainless steel mesh, and it improved, but still not like in my vivi's or cartos. I prefer the vivi's as I can rebuild them and also clean the heads pretty regularly.
I'm just sharing my experience, I'm actually quite a noob, but it was a frustrating deal and I just wanted to share what worked for me.
