I have first hand experience in this. Yes I believe the bladder is thinner.
I have three 2012 LW kites and last fall I had the 13M kite blow the leading edge bladder just after pumping it up on the sand. There was nothing sharp nor was it folded. I don't think they can take as much pressure. The kite was brand new used about 5 times. I have owned 2009 to 2011 Cabrinha's.
I never treated this kite any different than the rest. I think they made the bladder's thinner to save on weight hence LW kites. You have to be a little more gentle with them.

My friend has a 2012 14m Cab' Switchblade which uses the thinner material. He is an experienced rider and never abuses his kites. He is also a dedicated to Cabrinha having rode their SBs since 2008 and owning several, Contras too.
3 weeks ago he blew the leading edge while pumping it on the beach (only 1/2 way pumped up). I helped him pull the LE whereas I remarked "WTH?? - this material is super thin!!". The LE experienced a blow out near a strut 8 inches away from a valve. Upon inspection of the blow out it was a typical "stretched out and blew" scenario. Upon inspecting the entire LE we saw several small stretches (aneurysms).
The local Cab' dealer filed a warranty claim for a replacement leading edge bladder BUT Cabrinha had NO LEs in the entire USA for a 14m so they sent it to the BLADDERMAN in Florida who repaired it. Cabrinha asked the dealer to ask the rider how he put away his kite - did he roll or fold it? - he said he folded it - Cabrinha said that was the problem - you must take care and gently roll it.
I have never heard this in my life and think it is a BS answer
Two days ago we reinstalled the repaired LE. We inspected the LE for no twists and no voids, massaged the LE into position to get any wrinkles out and after pumping it up 1/2 way it blew out this time in a different spot. When we contacted the dealer she said .... Oh, you installed it wrong. Another funny answer IMO
The purpose of this email is to see if anyone else has had problems with the LE (I am not slamming Cabrinha because I think they make great kites. I DO BELIEVE that using this lighter material for the sake of reducing a few grams or weight is a big mistake)
I read that Cabrinha is using even thinner bladders on their new Velocity. Kinda' made me a little concerned about durability but I guess the best way to ensure durability is not to crash the kite.
I had a 2012 Cabrinha CB that had a thinner bladder than my 2010 CB so for sure they have gone to less material. I don't claim to understand plastics durability but you would think less bladder mass would equate to less structural integrity.
I haven't popped a bladder (yet!) but have had do some preventative maintenance on LE seams where the stitching has come away. This has been a problem post 2010 kites when the seams were changed, ironically for durability. My 2010 kites (SBs) are in better condition than my 2012. Maybe this was fixed for the 2013 kites.
Once the stitching wears, it does not take long for the seam to start parting, and the bladder to appear. Not sure if this is relevant but from what I have seen and heard, this is where the bladders usually burst.
I've popped two LE bladders in the 10 odd cabrinha kites I've owned over the years. A 2007 contra and a 2010 SB. Both kites were well used when it happened so I was not really upset. The reason for them going according to the repair guy was the double stitching on the LE material had starterd coming undone and at some points there was only a single row of stitching keeping the bladder from the outside world. The one popped in the process of a self launch and the other popped while I was pumping and it was only about 70% inflated. Other than that I have never had any other bladder issues.

That stands for 0.06mm, which is only 0.00236 inch
My 2012 Switchblade 14M just started leaking. Upon inspection there are more than one hole and more bubbles ready to pop, I always try to under inflate to help the bladder last longer, but it only last one year.
So on inspection my blown bladder was definitely as a result of a fold twist. What I believe has happened is that when I blow my kites up I do not unfold them fully on pump,ip. I just had let them blow up and unfold. Sometimes I remember that I had to assist with the last wing tip area as this got caught on the bridle.
My lesson........ Unfold my kite completely on pump up.
