If you have different tanks that you swap between , with different output then dont bother with the g6r. The regs must be adjusted every time input pressure changes and you should use the pressure tester each time.
If that is not the case i dont see why you would shoot a axe over a g6r. G6R is lighter, Better trigger, Better ergonomics, Better battery life, Better efficiency, Much lighter, much sexier . Only other downside is "to me" that it is a stack tube .
The Axe may have a good sound signature when it has a boss bolt and if you dont like stacktubes its a single tube-
I have owned both and would never pick up a axe to replace the G6R even though i love the mini\axe platform. The timmy is just that much better.
There are also multiple videos showing the clone getting what would be 11 on a full fill. All depends on which ones you watch. Also, most people who've had them claim around 11 pods once broken in. I do not know, unfortunately, how much quad mod'ing makes a difference though. I haven't shot a DM14, or a 2.0, but I have shot other luxes, and every DM from the 4 to the 12. I've played days with them, I know how many pods I got from them. Same with the Clone GT. With full fills. I can only go by my personal experiences.
My Clone GT would do no were near 11 pods . Thats why it got sold together with the regency crome 2 . Could not be used for the local woodsball field were they have maximum 3k fills.... The GSL i bought this January though is way closer to that efficiency claim.
It should be durable most PE guns are . I dont know anyone who had serious issues with the Etha yet and if you had the Customer service is exellent. It does have a closed bolt system unlike the ETEK so its harder to get dirt into the gun as well...
