VPI Flywheel or Fishing Rod Wire on Aries Motor?


I realize that VPI has some other upgrades that may be better than the integrated motor/flywheel, such as SDS and the ring clamp. Assuming that an owner already has these (I'm planning on getting them), how significant an upgrade is the flywheel? I have not seem much emphasis on this product from dealers. Is this, perhaps, an unsuccessful upgrade? One downside, it makes for a larger footrprint table, making it extend beyond most typical equipment racks...this issue may account for its lack of popularity? I have heard that just using an Aries 3 motor with fishing rod wire (e.g., SpyderWire) is a good alternative. Any thoughts would be much appreciated.

I bought the Teres Verus rim drive for my VPI and immediately sold my motor/flywheel and SDS. never looked back and as a bonus fits nicely in the cutout of my Scoutmaster. Better in everyway IMO
Thank you for your response. I have been seriously considering the rim drive. I asked VPI about it a few days ago. They said they had not tried it, but that they had heard from one of their customers who tried it and went back to the SDS. Maybe I should order it on trial. I have read online about others who also had positive things to say about it...
Spyder wire and other synthetic fish line is unacceptable for the VPI motor due to complete lack of elasticity. It needs to be tensioned very tightly to grip, and then acts like a plucked piano wire to transmit AC motor cogging as audible quavering. Cotton/poly, poly or silk thread must be precisely tensioned, but when this is done they sound both livelier and more speed-stable than the stock soft rubber belts.
