Jaros threw both balls but you don't know if they were layed out the same. I have both and agree the Bounty moves earlier and hooks a ton while the S-75 goes a little longer and has a snappier backend. both my balls are drilled the same and have been shot on pba layed out patterns and house shots, The Bounty hooks up early and rolls strong to the pocket where the S-75 snaps to the pocket. When lanes dry up a bit I can still throw the S-75 but have to put the Bounty away. I hope this helps a bit.
