what you want, what the entire industry should give us, is threaded inserts in any cartridge body, so two fasteners from the top are all that is needed, so easy to set overhang and null points alignment.
if every headshell had azimuth adjustability, that would be nice
open sides makes it easy to deal with the wires
I prefer removable headshells, and I like how Micro Seiki 505 arms have an adjustable fitting for easy azimuth, another industry standard I wish existed, then no need to adjust the headshell itself.
VTA, easy smooth arm height while playing/listening exists: no tools, loosen locking lever, rotate up/dn, tighten all by hand: examples:
micro seiki
acos lustre gst-801 (I learned about mine here when I joined in 2019)
technics EPA-B500 Adjustable Base also has removable straight and s arm wands
52mm overhang? 52mm must be specific for something else, overhang is the distance from the spindle to the stylus tip centerlines, the longest I have ever set is 15mm, I’ve never seen a protractor beyond that.
square to the headshell, not relevant, when aligned to the two null points, may be slightly off-square in the headshell.
