I have repeatdly stated that balancing is not required.
1. is a production shortcut
2. cheaper than the time consuming tolerances or .005 at the ends and hold to .012 in the tube middle &phased correctly
3. not enough rpm's to be of a concern anyway if done correctly.
4. almost is what you have now and it's wrong. Go figure.
I get your point
Finally... I am a bit slow sometimes
