What's your budget?
If you want something low mass and high compliance, there are still new Ortofon OM20's out there:

If you prefer the Shure sound, the M97XE is a possibility, although they supposedly sound alot better with a Jico SAS stylus.
And there are plenty of Audio Technica or Grado options that would work fine with your tonearm.
EDIT: If you'd like to try a low mass, high compliance LOMC on it, I know where a Sony XL-MC1 can be found.
