Sooo.... after i figured out that all i had to do was let the juice sit in my Vivi nova for a while (over night in my case) to not get that burnt taste without rebuilding the wick/coil. I realized that i LOVE the flavor and vapor off these tankes. The draw was real tight in my opinion though. I was a little bummed at first, BUT since i thought i broke the wire on one last night i decided to take the center post out and check. When i did that i noticed the TINY air hole in the top of the center post. I figured this was where the tight draw was coming from so i cut off the nipple with a file and widened the hole very slightly. This thing hits like a champ now!! Anyways thats my small modification to the Vivi Nova tank! Hope you all enjoy it as much as i do so far!
