I have 2013's also in 10, 12, 14m - no bridle adjustments (bummer), but they are still damn good performers in all categories. I am very happy with them for teaching, and can still have fun on them myself.
I am also relieved to be back on a single front line safety because ditching the kite/ self rescue is a regular part of my lessons.
I don't believe in the IDS type/ mini 5th (two front lines) safety at all- most aren't even close to depowering the kite.
If I had a complaint, it would be that the left side of bar itself is white instead of red. The float and leader is red, but a red grip would make it even better.
