I found this for sale locally and without doing my due diligence bought the equipment right away. Now I've researched the Axe a bit, but have no clue when the white edition was released, and the used price for them is kind of all over the place. The air tank is from 2013 and is a 4500psi unit with a "pro" regulator.
Just for reference, I used to be very active on this forum back when I was in college in 2007. Sadly that account was tied to my college email and I can't access it. I'm completely out of date now and am not sure whats what in this sport these days.
