No experience, but I saw this video the other day. Seems like a decent overview of holding torque and tuning.

Great thank you.

I did see the video where he testet steppers also. Good stuff.

I guess the stiffness shouldn't matter too much when coupled to a ball screw - at least it should be possible to calculate how much deviation it would have.
Also I think maybe with proper tuning it should behave differently. But that might not be easy to do without proper instructions.
