Hi,
I 'm using a RSR 10.7 (+Amex550/X9U 530) an I've borrowed a RSR evoII 10.7(X9U 530) last summer. I much prefer the RSR rather than the EvoII. The evoII construction is so poor that after 5 hours of use, the sail became quite unriggable with cambers not rotating smoothly (far from that) and with a huge volume in the front giving lot of power but quite unstable.
It would have been probaly much better with 2/3 more centimeters of downhaul but It was not my rigging.
My personnal conclusion is that the RSR is doing the job great and that it's not yet time to change. The nice point is that you can find a RSR10.7 in very good shape at 300€/350€. Probably the best deal you can do.
hope this advice will be usefull
