Also got one.
Very good speed sail; great early planning, insane ammounts of power, great stability, big wind range, and great top end speed. When I changed from 07 koncepts to the 5.8 RSR it seemed to cover the 6.6-5.0 KA's wind range..... Only downsides are problems with batten/cam breakage (easy to fix yourself though), and increased sail weight relative to most freerace sails.
