We all know the protank has an airy draw and the replacement heads are nowhere to be found yet so here's a very easy way to fix both problems - mod an evod head to fit the protank and at the same time fix the airy draw (makes it similar to that of a vivi nova, maybe even a little tighter - for me it's perfect)
Very simple - take an evod and protank head and remove the posts (I also took the top wick out of the evod head - seen here on the left):
Put the longer protank post on the evod head like so:
The posts come out pretty easily btw, just yank it out w/ needlenose pliers - might have to shimmy it back and forth a lil. You can actually use the evod head in the protank w/o any modification but I find it hits a better if you switch the posts.
That's it, taking out the top wick isn't necessary, I find it hits better for me but the great thing about this is not only are evod heads cheaper and in stock everywhere, the bigger o-ring serves to tighten up the draw significantly. Perfect fix.
