I have been using 2014 bar on 12m 2013 kite all summer. I honestly can't feel any difference.
That being said if you go to the cabrinha compability chart it says it is not capable. When I ask the Cabrinha dealer they said the words from Cabrinha was yes.
I have also flagged it out several times so I am pretty sure there is not safety issue.
@Scoish thanks for the info... So you didn't notice any kite performance difference between the 2014 bar and the 2013 IDS bar on your 2013 SB? If so that is good news... I know the 2014 (and now 2015) bar is backwards compatible and the safety systems work just fine. Cab's position on using the 2014 bars on 2013 kites (esp the switchblade) was that the lower V on the 2014 bar "opens the arc" on the 2013 Switchblade which they say makes it fly a bit differently. And they state while it works fine, the 2013 may provide better flight characteristics. So that is what I am trying to get info on: The kite flying and performance with a 2014 bar compared to a 2013 IDS. Seems like you are saying you didn't notice a difference so that's good enough for me! Someone else told me the 2014 bar makes the 2013 SB actually turn a bit faster.
Anyways thanks for info!
