I've been vaping VN since I moved from atomizers to tanks. I've tried a few other like the pro tank and the AMP Tank, didn't like either one, both leaked and gurgled a lot. 
  
  
That being said I do need more than what I'm getting out of the vivi nova's 
  
I'm considering either the Kir Fannis Prive tank (if I can find one) or the Lil Mama tanks. 
  
If anyone has some input on either of these or both I'd appreciate it. 
  
Thanks
