Clearaudio MM's do not work well in wimpy unipivot arms - they push the arm around in azimuth too much. I sold my VPI 10.5 and bought a vintage Zeta Black. The difference was night and day.
Get an arm that is stiff in azimuth, like an SME, and it will handle any combination of cartridge weight and lateral compliance.
