Soundsmith Optimized Contour Contact Line Stylus for Rebuild

I am having a cartridge, a Lyra Clavis DC "rebuilt" by Soundsmith.  I am considering a Soundsmith Optimized Line Contour Contact Line stylus on a ruby cantilever.  I'm asking for opinions of those who have used this stylus, the pro's and con's of the rebuild and whether it changed to sonic balance of the cartridge.  I guess I'm asking opinions on the success of the upgrade and whether the rebuild met or exceeded expectations.  I haven't made the final commitment, but the cartridge is in the hands of Soundsmith now.
