Good call, @abbey road d enfer. THT all the way.

Final Schematic for reference:

Gerbers are on Github, and will be updated as the project changes.

C9 and C11 could be smaller. C11 could be 10-22uF, and C9 could be a ceramic 1uF. The latter wouldn't be much smaller but it would have less leakage.
