Lefty,
I have had both, and still have the Bank in the bag. Let's compare the numbers first.
Bank
S73 at 4000
2.48 RG with a diff of .054, and a intermediate diff of .020
Bounty
S77 at 1000
2.48 RG with a diff of .054, and a intermediate diff of .021.
Similar numbers, stronger cover on the Bounty.
That being said, my Bank is clean thru the fronts, reads the mids really well, and actually takes off on the backend. The weightblock in that ball is great, causing it to roll very uniquely on the back.
My Bounty was very smooth. Too smooth for me. OOB, it was too early for me, causing carry issues. Polish allowed me to play further right with that smooth look, but I couldn't justify using it over my S75 or my Black Break.
So, if you want smooth, go with the Bounty. A little stronger on the back, go Bank.
