After Jim "reset"/checked HEPI this morning, we went in and removed ~3mm worth of shims from the main chain.  THis dropped the main chain down, removing some more of the height error.  Note, we have no more shims to remove, so we'll need to be crafty in dropping the suspension masses further.  Jason reports that we are still ~a few mm high (number to be reported by him shortly).  We are wondering if the +3mm HEPI adjustement that was required for the ITMx-PILOT optic install months ago is needing to be undone now with this "real" suspension.  We'll need to track down if we had a short pilot suspension compared to the monolithic we are installing now.
