Post the mass of your tonearm first, because recommendations here are blind, some cartridges are not compatible with your tonearm (if a compliance is too high or too low). 

The arm mass is 10.2 gm

With that effective mass you can get away with a myriad of medium to high compliance cartridges. Perhaps you could even lower the effective mass further by adopting a very lightweight head shell, if your tone arm has interchangeable head shells. In any case, be prepared for an avalanche of suggestions, all different, all adamant.
