Hey, we own the same table. I would take a look at the new Series Six arm by Audiomods in England. Carbon fiber arm tube, ceramic bearings, uninterrupted run of silver wire from cartridge tags to KLEI RCA plugs, variable-mass counterweight, azimuth adjustment, micrometer VTA. Reasonably priced at 985BPS.
If you want an arm that is well known to be a beautiful pairing with the Rock Elite, you can look for a Zeta (that's what's on my Rock), then send it to Johnnie at Audio Origami in the UK for rewiring. He knows the arm well, and offers a variety of silver wire, as well as Cardas copper. The metal arm plate that came with the Elite is even drilled appropriately for the Zeta!
