Please do not top-quote, it makes it difficult to create a readable reply. :)

In anycase, have a look at vtkInteractorStyle.cxx, and especially at the
HighlightProp method.  

Unless somebody else has a better idea, you're going
to have to derive a new vtkInteractorStyle class.

You could:
1. derive a new vtkInteractorStyle class.  This is probably going to be more
   trouble than it's worth.
2. use AddObserver on the RenderWindowInteractor to add a callback for
   vtkCommand::EndPickEvent.  In this callback, call HighlightProp(NULL) on
   the associated InteractorStyle.  This is a bit kludgy, but it has high
3. Do not switch off the visual feedback.  It's quite handy.
