Actually, some of the older reflex 7.0s have a 463 setting with a recommended mast of 460.
However, a 430 with a longer extension should still be fine.
I've noticed that this years 6.5m NCX has a 463 setting but a 430 mast is recommended. Would prefer to just buy a 460 mast Blueline that would go with my future purchase of a 7.5m. Rigged it with a 430 gorilla rdm which was ok, however the leach was floppy all the way down to the clew nearly on the recommend settings. Still went pretty well but will try with a 2 cm less downhaul next time.
