TONEARM for Tsd-15, and SPU's

I will be auditioning a Luxman PD171 at a dealer in the next week or two. I will be hearing it with the PD171 standard Jelco arm. However, I may order the table with a higher Jelco, an SME M2-9R, or an Ortofon 212S or 212D. I would ideally like to get the arm that will match my tsd-15 well, but also allow me to delve in to SPU's with confidence. My Tsd15 is the SFL, not in traditional headshell. However, I could always opt for my next Tsd-15 in the traditional headshell. The SPU on my radar is the current production Royal GM II.
