Using Ceraballs, Cerapucs and Cerabase on FE Spide

I would like to know whether any FE Spider owners have used Ceraballs and Cerabase on the Spider rack. I am particularly interested if the Cerapuc or Cerabase replacing the spikes at the bottom of the rack will bring further improvements when all components on the Spider rack are already supported with Ceraball Spider on the cross bracing.

I would appreciate your input.

Thanks in advance.
