Can't attest to anything about the rorys, but the prophet 100's are terrific.  If you are looking for a ski that can do it all, on any terrain in the mountain, you can't go wrong with the prophet.  I owned a pair myself, and they were great.  Not stiff, but super solid, and still pretty turny because of the sidecut.  The only place I'm not sure about them in is the park.  Something weird happened with them though.  When I firs bought them, they had a minimal amount of camber, and regular tip and tail.  As expected the camber flattened out with use, but I think because of the titanium bending, the ski has turned into almost mini hellbents.  There is rocker that goes approx. 10 cm further than the regular into the tip and tail.
