Sound Smith Retip of DV 20X2 Cartridge

Anyone use Sound Smith to retip their Dynavector 20X2 MC cartridge? In particular, I'm thinking about retipping with one of Peter's higher end ruby cantilever and stylus versions. Comments and reactions would be welcome.

My main carty is the SS VPI Zephyr, which is a fine sounding cartridge. The DV 20X2 is my back-up. I personally think the Zephyr is in a different league.

My TT is the VPI Classic and phono pre is the ARC PH-8.
