Have you used a DSS wing with a compressible "wobble stopper" ? These work much better than hard rods in previous designs.
Such a design can actually be more secure than a STA because STA's tend to pivot on the bolts used to secure them to the back plate. Remember between the STA and the back plate is usually a less than flat metal grommet in the wing and or the harness.
