Cartridge Recommendation for Grado Lab Series Wooden Tonearm

I have a TD124 with the Grado Lab Series wooden tonearm. I use a Nakamichi Ca-5 preamp which can accommodate MC and MM cartridges.  I can't get specific information on the mass of the tonearm, but understand that it is low mass.  Am looking at Nagaoka MP150/200 MM and Denon 301MK2 MC.  I listen to all types of music.  Any recommendations in the $300-$500 zone?  What do you think about MM at this price point versus MC?  The rest of my system is B&K AVR505.2 and Sonus Faber Domus Grand Piano speakers.
