OKay...
First thing I see is that the tip of your pole is unsupported and in high winds might break off, I would suggest lines running from the bows to the tip of the pole to fix that.
Then don't worry about the moving pole and just get the thing centered and stabalized.
Secondly, the line (bungee cord) attaching the pole to the bridle wires needs to be solid and not stretchy. Use a piece of low stretch line and using the lines that you will be attaching to the end of the pole apply enough pressure so that the pole is slightly bent downwards, this is known as prebend and also helps the pole from breaking.

Others have tried the moving pole and didn't have much luck. Cats are fast enough that the appearant wind is very far forward and the moving pole just isn't needed...or at least that is how I understand it.

But cool rig and be ready to get ripped apart.
