The weight recommendations for the USM are guidelines only. The reason we specify a max weight for angled or horizontal is because heavier microphones will make the inner ring of the suspension sag slightly towards the outer ring. This is more of a look problem than a performance problem, unless the rings hit each other. If they hit each other then the suspensions performance will be reduced.
There is however almost zero chance of damaging our suspensions from use with a 725g microphone, so I would confidently say that the InVision USM would be good for the Bock 195 for drum overheads.
