Speaking about Triplanar weakness. My Triplanar VII ''refused'' to
track anything above 50 microns on my test record. Even carts which
easilly got 70 microns right (aka ''pure'') on my FR-64s were not
able to track more than 50 microns with the Triplanar. I know that
''induction'' from one experiment does not count as proof but
anybody can repeat the same experiment and see for himself.
