I own a Grace tonearm and two Grace Ruby cartridges. I was surprised to read that Grace and Sumiko could be associated, because I have never particularly liked the sound of any Sumiko label cartridge, whereas I count the Ruby as one of my all time favorites. Raul mentioned that I had one of my Ruby's re-tipped by Sound Smith. I opted for the OCL top of the line stylus on a ruby cantilever (of course). After a pretty thorough trial, listening to it not only on my system but on Dave Pogue's system as well, I (and Dave Pogue) concluded it sounded "bad". (Details elsewhere, but all the faults I heard on my system were immediately evident on DP's system.) The cartridge then sat in a drawer for over a year, after Peter Ledermann invited me to return it, and I just now sent it back to him for their evaluation. (My bad; I just hadn't felt the need.) This is not meant to reflect badly on SS; obviously they are capable of great results, and they are beyond reproach when it comes to ethics. Either my particular mounting was defective, or the OCL does not work well on the Ruby. Recently, I connected with someone who told me that he knows of two other persons who were not pleased with the OCL/Ruby comparison and one person who is ecstatic with his SS "level 2" line contact rebuild of his Ruby, claiming it outperforms the original elliptical. So, the less expensive option may be the way to go with the Ruby. On the other hand, maybe Dave Garretson had a different experience with the OCL. Dave?
