I have one that uses set screws in the cones, and a negative side effect is that the cone is pressed firmly to the shaft on one side with play on the other. It's out of balance at that axle before I start. Genius indeed.Also, on my balancer, and I believe on the Marc Parnes as well, the set screws in the two cones that secure them to the shaft do tend to mar the steel shaft over time and multiple uses, especially if you get a bit over-zealous with the allen wrench.
With the clamp collars that FJReady uses, that will never happen.
Genius!
