3D Dynamic Ball Bounce

The ball bounce, it does have the squish and it does stretch but, there is something missing, i know i've missed something, it could be because it is too smooth, it doesn't have sharp enough bounces. it could be the action curves now that i think about it. the understanding is there, the ball stretches in the air as a connotation of fast movement, and its squishes when it comes into contact with the wall.
one other thing, this rig is by far the most annoying, i've tried the larger merry and Ellie rigs, that are much more complicated and found them easy to understand, but this ball rig, is frustratingly hard to understand, i don't think much effort went into making it.
