Well the video is fairly relevant.
You do have 3 main way to connect.
Yellow flagging line. I use this if it is one of those super crazy days.
Depower line. This is the connection I use the most. Best for the easy self land and launch. I guess you could do depower line and yellow line if you are afraid the depower line will break.
And Chicken Loop. The new leash accommodates for cl and yellow line so if need to release the CL you can and still not lose your kite.
I think there are a few notable differences that the video does not depict. And that is the housing on the CL is different. It is much easier to power and depower with the 2012 bar. There is a spinner, and the yellow line now is less in the way I think.
