As an aside, I am also comparing the AT20SL cartridge with the AT20SLa. Upon casual inspection, you don't really notice a difference in the two. But Rusty clued me into the fact that the AT20SLa has a slightly different cantilever angle. When you hold them side-by-side, you can see this:

The original AT20 cartridge is on the left in all three photos. The AT20SLa is the same cartridge electro-mechanically, but it is slightly shorter and the stylus mount is angled differently. As a result, the vertical angle of the AT20SL is 20° and the AT20SLa is 15°.
