I have now tried the Reflex IV 10.7 with a 530 red-line mast (using a regular base extension) and I think it works quite well, at least in the light winds that we had. My weight is around 70kg and the low end is more important to me than the high end, so a softer mast, and sail, works better. As soon as the wind picks up (above about 14 knots) I'm much more competitive on the 9.6 anyway.
I love the chamber rotation on these sails, a slight breeze is all it takes, no kicking anymore...
