Interesting that we tried to steer away from the Proctor arms on Agent Orange and the Rhino Grey Taipan as well for a few reasons 1. expense 2. simplicity 3. style. Attached are the photos of the epoxy arms we made to fit the Goodall Wing.

In our local fleet most sailors aren't too concerned with varying the rake on the arms. We opted for simplicity in that the 'ezi-tune' system is just 3 slots cut into the outer end of the arm which allow the rake to be varied.
