I ran my YS110 (old style) on the hyde mount with and without the nose ring in a wooden airframe (Voodoo Express 2).

Without the nose ring, I could visibly see the spinner moving laterally both in vibration mode (kind of blurry at the tip) and in offset as the throttle was raised and the torque effect pulled it off to the side. Not horrible enough to hurt anything on the airframe, but definatley noticeable.

I added the nose ring and was astounded at the difference. Of course all of the lateral nose displacement was gone, but it was also amazing how much quieter the whole setup was.

IMO - If you can run the nose ring, it is absolutely worth the effort. If not, it will still work.
