I have been using Kanger T2's and I have vaped blackberry, menthol, and wintergreen from vaporrenu, cappaccino and ry4 from mt. baker and red hot candy flavor and heavenly tobacco from heather's heavenly vapes. just got some evods in the mail (absolutely love them). I don't trust myself with the protank because I work for the railroad and carry my ego in my shirt pocket. Out of all the juice I've tried, HHV would be the one I will order from again and again. Her flavors are awesome! As far as Vapor renu goes, I will order menthol from them. It's good and cheap. I probably wont order from MBV again. Liked their juice the least out of all three.
forgot to mention, the only problem Ive had with plastic tanks was with the ce4's that came with my kit. They were the best vapor producers by far, but not able to handle all juice. The kangers are thick and tough!
