I have to say, this bracing system has not improved my prints, but has ABSOLUTELY TRANSFORMED them.
Ringing, which was bad on my setup over 60mm/s, has completely gone, all the way up to 135mm/s. Whodathought!
Combined with the good old squashball feet, this little bugger rattles away at even 20 on jerk and 1000accel for print moves, and just doesn't ghost. The extra wobbling movement that the feet gave the unit took a bit of ghosting away, for sure, but both together - again - stunning results. It just rocks and wobbles away in the corner now, but there is absolutely NO movement in the Z axis at all.
Superb mounts, excellent result, well thought out design.
