Well we all know that the protank can use a couple different heads but i'm curious to see what heads some of you prefer in your Protank 2's. Do you stick with the PT heads or go with Evod or Davide or what? Seems my protank could use a boost in performance because right now im not happy with it so maybe its the PT head im using. Is there something better that is compatible with this tank? I like to use this on my provari btw.
