Have anyone replace VPI SSM belt with string?

Most heavy platter tables like Verdier or Micro Seiki use silk or string to drive the platter and reason is obvious. VPI SSM or HRX both have heavy fly wheel that motor has to drive. I can hear my VPI SSM belt noise when it is not perfectly clean and will wobble and shudder especially running at 45RPM. This is more obvious on the two small belts driving the flywheel which much more work than the long belt driving the platter.

Has anyone tried using string or dental floss to replace the belts on VPI tables? I know for SSM or HRX, making two identical length strings for the motors will be extremely difficult and that means different load for each motor. But is this idea feasible at all? Are there any downside to the string?

I tried this a couple of years ago on a VPI HW-19 MKIII using silk thread. You will need a motor controller to get the right speed (I used a Phoenix Engineering Roadrunner).  Ultimately, the set-up was too much of a PITA. Although I liked the sound somewhat better, I went from having too much bass to not having enough. The thread slippage was always a problem for me.  I was using a clear belt. VPI's black ones are much better IMHO.

I now have a TW Acustic TT.
