I don't own both balls, but I know someone who has. For him, the Backyard is about an arrow weaker than the Absolute. The BYB is cleaner in front and pushes more in the midlane, and makes a stronger move in back. Both are drilled with pin above and to the right of the ring, CG near the palm, no XH.
Hope this helps.
