I’m super impressed with the amount of work You put in to your answers. I will Of coarse keep working on the different ball actors each with there own solution Until I can find one that works. My concern Like Richmar1 said is that Physics Might be unreliable for my goal As the players Is hitting the ball around In VR with a racket and it will need to feel right.
weirdly enough I cant even make my actor with the movement component move Not sure why . I have copied all your settings.
Update:
Ah sorry It does Move , Its just I was not hitting it. 
But both these solutions seems to behave correclty from my Hit with the racket But they Like to roll down surfaces to much and the projectile Method Is Not Acting strange.
