I've been watching for a reply to your query and can't resist replying any longer.
The MG-1 looks interesting although the maker isn't selling it outside the US at present. Outlier who posts here has fitted a Zyx but did have problems with it jumping.
The manufacturer is the best person to tell you its effective mass. My hunch is that it's quite low and you're right about low compliance cartridges not matching. I would consider the higher end Grados, a Musicmaker (which is the cart of preference with the Opus2 Cantus passive linear tracker) or even a Shure V15.
