I would post this in Blender Tests, this forum I believe is for finished animations.
I agree with you though the second one is too wiggly.
I think Nathan Vegdal did a great job simulating fat in BBB, I’m pretty sure he just used bones. Some of us spend too much time trying to make the software “do it for us” when it could be hand animated easier and more quickly, with much more control over the final result. As far as the time required to animate a jump, yeah try a flip or a cartwheel!
