We can also use polygons, angled lines, or arcs to form the teardrop.
My thought though was simply to make the via a little thicker on the

If you look at my original post, you'll see that I did arc-based
teardrops on the other side of each via. They don't add much
protection against off-center drills, but they do add strength to the
joint by removing a sharp inside angle. Sample attached.
