New cartridges should all come with photos like these

The two cartridges belong to my friends. In my inspection I believe the cantilevers were both overly steep, resulting in the SRAs in the +96-degree range when the top surfaces were level. After adjustments at the factory, they came back included photos showing much more reasonable angles. For the cartridge manufacturers, providing such photos should be fairly easy, and such material will greatly help the users in correctly setting up the devices. Additionally, this makes monitoring the health of the cartridge much easier over time.
Note the angle of the coil is now only slightly away from parallel to the pole pieces. Adding tracking force and drag should put it into near perfect angle.
