This is different but it works. I'm right handed, put my thumb down at 7:00 and fingers up at 1:00, release soft w/ some reverse rotation. Ball goes dead straight most of the way then turns over a couple times. Usually hooks 2-4 boards at very end. Started this about 2 mo's ago, have not missed a 10 pin, 6-10, or baby split since. Best to use a dark solid colored ball as rotation looks horrible going down the lane, but can't argue w/ success. I don't carry a spare ball anymore.
