I should warn you that the stretch that the package performs does not preserve the vertical stem widths. Therefore, especially at small point sizes, there are perceptible weight changes.
In my opinion, the default font expansion value stretch=20 is not conservative enough. I would personally recommend not only reducing it but also using the selected argument to further reduce the expansion of glyphs whose geometry distortion may be more easily perceived.
