Also for this one I was playing around with the timing and not just the spacing. The last animation was done on mostly 2's except for the contacts with the ground which I changed to 1's later on. This one was done a bit the same with the "light" ball on 3's and the heavy ball on 2's with both of their contacts on 2's and 1's.
Here it is so far!
Here's a higher quality one as well
Enjoy!
