Has anyone worked with the Pre-made L-Styli?

[[Au...]]

I'm looking at them as a possible replacement to the disk probes for particularly small grooves, partially because of the inability of our current disk probes to get into some of the finer grooves, and partially because using disk probes with calypso is just not ideal and a bit of a pain. Looking at the catalogue I noticed https://shop.metrology.zeiss.com/INTERSHOP/web/WFS/IMT-US-Site/en_US/-/USD/ViewProduct-Start?SKU=626113-5000-187 this item. Before asking for my superiors to order this pricey probe, I do want to know how it performs in the real world. namely how you ensure that its rotated to the machine axis? are the Zeiss threads precisely measured to clock the probe? or would it be a matter of either rotating the head to the angle closest to making the probe aligned, and using a conical adapter to align it on a duramax? Any more significant info on these probes would be appreciated, or if Zeiss already has documents on this, I am a huge fan of RTFM.
