Pins are nice and work really well for larger holes BUT with the microvias
they probably won't serve the same purpose or success.

The reason for this is that the center lines of the vias are rarely the same -
to me that is one of the main problems -

In a row of microvias you may be able to look at one at a time due to the
slight misregistration of position.

We use pins (2) - we drill their location with an Excellon Unidrill - but do
not
rely on all vias coming into view at the same time.
