Too many Old Fashions have caused some unnecessary teardrops.

Subject: [TN] Validy of Teardropped vias?
Hey Y'all,
It is my habit to teardrop a trace coming into a through-hole pad if the
trace is 5 mils or less and the annular ring of the pad is 5 mils or
less.
Does this improve manufacturability of the bare board, protect against
drill-out, and fracturing of the point where the trace enters the pad
under shock and vibration?
Or am I an old-fashioned girl?
