Does you Pioneer arm require the normal 52mm overhang alignment? You may have difficulty with the AT headshells getting the correct overhang. The MG10 and MG100 which I have all come up slightly short on the front holes until you shim it with appropriate gaskets on the plug.

Also, I would be very careful about going much higher than 10g depending on the effective mass of the Pioneer arm. The Technics arm is 12g effective mass. With a 9.5g headshell, the LF resonance was right at the bottom end of the "ideal" range.

If you go for a heavier headshell like the 13g or 15g AT, then you risk negatively impacting the sound due to the LF warps causing the cantilever to start bouncing around at a greater amplitude than with the stock headshell which will cause poor tracing and tracking.

I was recently playing with a Denon DL301 which is a fairly high compliance design. In the Stanton headshell, the LF resonance is about 7Hz. Once I remounted it in the stock headshell which is 2.5g lighter, the sound is much cleaner with really well defined, tight but very extended bass.
