T&T: Racor 2 micron vrs 10 micron

[Chuck Shipley]

Others have said as much, but somewhat more obliquely.   Jeffrey has put it
out there in plain words.   He wants the secondary to be "used and
operational", i.e. useful.

I don't, because "being useful" means getting dirty, and getting dirty means
all-too-soon needing changing.

To me, wanting the secondary to be useful is like a football coach insisting
that the defensive line let a few ball carriers through so that the
secondary will have something to do.  :-)
