So decided that the old double bubble screen which has started to crack internally & has snapped locator lugs under the mirror mounts needed to be replaced. After a bit of searching the MRA screen whilst expensive looks the best.
Before = Old Screen

The MRA screen is a little lower than the old one. Measured from the front of the steering stem bolt, old screen was 14.25" above, MRA is 12.5" above. At speed you need to tuck a little at 100mph to get the benefit from the new screen, old one was good to 120mph before you needed to tuck. At lower speeds they are much the same.
