Other than this issue on my 12 meter, I have been very happy with the NRGs. Great kites. I also own a 2013 16-meter NRG and 2012 10, 8 and 6-meter NRGs - no problems with these.
Damned man, you are Mr. NRG!
I have a 2013 16m and 12m, no bladder issues so far, cross me fingers it stays that way; I try to baby my kites (no tomahawking) in the hopes they last. I'm surprised you went for the smaller sizes, once the wind gets up that high I start to like other designs better
To the OP, hope you are able to sort out your issue, let us know how you resolve it. One thing to consider is simply getting a new aftermarket bladder. Granted, if you are within warranty I can imagine you would prefer to go that route. These guys manufacture their own altho the main LE is expensive (the struts are actually quite reasonable so anything other than the LE should be easy - of course, thats the problem you are having).http://www.airtimekite.com/index.php/li ... dders.html
