I disagree that it's "common practice." I rarely see this, and never
do it.

Perhaps it should be, "not uncommon?" Anyway, thanks for the comments -- I
respect your design capabilities John and it's clear you have a good mind for
what works and what doesn't. (I probably spent too long in school as I seem
to often be overly conservative when it comes to such matters. Although I'm
not as bad as one professor I had for a microwaves class where who was
cautioning a student who'd designed a ~3GHz stripline filter that moving his
input or output SMA connectors even a millimeter off-center from the
microstrip would "very significantly" affect the board's response... :-( )
