You may have noticed that there are actually four styli for these tiny-shanked bodies that are, or appear to be, virtually interchangeable and which I've come to think of as the same for so long that I forgot to mention that the S915E is really a "separate" stylus-- it's metallic silver. So we have silver, gold, clear yellow/amber --"S915E (yellow)"-- and metallic blue. Probably the Z styli got the most tolerance scrutiny in the QC process. I'm pretty sure the S915E came later (there's a whole series of S9## styli for some of the later carts, like the EXLs and others), so possibly-- possibly-- the bugs had been ironed out by then. Gary stocks the S915E, and it's also currently available on eBay for a reasonable amount ($47.30). Getting the T is more difficult, and even getting a Z body is a PITA.
All I'm saying is, if Empire ever built a stylus+cart for which they claimed a lower ETM, I haven't heard of it [I have now-- the 800 UFR 'Chunky' and the post-'Chunky' GT (aka Golden Touch) series, but the difference is small] and yes, 0.2mg (assuming any mfr's claims are even close to real-world, which is a big assumption, I know) is close to state of the art. Only a very few carts got under that [claimed] figure, and most used exotic materials to do it. So if one of the trio of styli should drop onto your work table, even by an accidental order on your part, you should get one of the special bodies. Not all of these have been confirmed, so shop carefully:
