- You can probably improve the quality a little bit by smoothing the
final mesh, i.e., by setting Mesh.Smoothing to something > 0. (The
default is 0.)

- I you're using Triangle (Mesh.Algorithm=3), you can specify the
quality the usual way (check Triangle's documentation to get the
explanation of the quality switches, and just put the string in
Mesh.TriangleOptions).

Best,
