Here is a good system I've seen on Infusions:

Place a micro turning block (surface mount) on the front cross beam either side of the mast so the line will have a good angle from the rotator arm to the turning block. Then run your positive rotator line from one side of the arm, through the micro blocks and back to the other side of the arm.

Install micro cleats with no fairlead/eyestrap a little outside these turning blocks on the front cross beam. This is what you will use to cleat of the line and hold positive rotation on the windward side of the boat. When gybing, uncleat it and then sheet/recleat on the new windward side.

You can also introduce a safety in case you forget to uncleat it (which could lead to mast damage on a wing mast): splice or bend some very skinny tweaking line to the either end of your positive rotator line and use this to tie to the rotator arm. This way if you forget to uncleat and there is a lot of force on the mast trying to rotate the correct way this skinny line will break at the knot on the rotator arm. I used a similar system on an A-Cat and it probably saved my mast on a few occasions.
