This is a very sensitive subject matter. Despite of this my advice is
to compare both arms with ''tracking ability'' test record(s). My Triplanar
can't track anything above 50 Mirons. Syntax mentioned the problem
with ''energy transfer'' by Triplanar. It may be the case
that my sample is defective but I was not able to find anything
wrong. Anyway carts which track 70 microns with my FR-64 s can't
track more than 50 microns with the Triplanar. I am sure that your
Micro is better in this regard.
