After doing some reading i believe that with twisted vanes all it should effect is the width of the diffraction spike as your mirror sees a larger vane than it actually is (because it presents a larger surface area) so you may be able to see this as the diffraction spikes getting larger and smaller. Though i cannot speak from experience and somebody else may be able to give you a much more informed reasoning behind the physics and resultant diffraction pattern.

Cheers for that Brendan
I have not had a lot of time of late to have much of a play with my setup to try and correct this issue. Hopefully get a chance this weekend.
