So neither Optimiser or Redondo is currently using 928 wheel and would rather use Si impeller over 928 wheel if you got to choose one over the other?

Hmmm....Kao told me Vortech wouldnt take my blower 100% unless I used their bearings, their impeller, etc.

Is this true or nah?

Yes Vortech are very conservative about ONLY using there parts and services on their brand. The other plus is that if Vortech do it you have warranty.
