Let the ball roll off your hand. You don't have to throw the ball 100 mph and have 500 revs to knock over 10 pins!

Sometimes you're the dog, and sometimes you're the hydrant.

 Juggernaut, I both understand and agree 100%  with what you are saying here, but some of us 75 year old "oldtimers" can no longer bend out knees like that and thus do have some back bend and I might add the results are oft what you have described when bending the back.

Learn to get the ball onto the lane using your KNEE BEND and NOT your BACK BEND.

 

 Bending at the waist (back bend) will change the physiometrics of your release, and cause your hand position to change from behind/under the ball to a weaker position closer to the top of the ball.

 

 If you don't believe it, take your ball and hold it in what feels like your release point. Bending your knees to get lower allows you to maintain good leverage and position. Now do the same thing, except bend at the waist instead of the knees to get lower, and watch what happens to your leverage point. It moves from behind the ball to on top of the ball, which is a much weaker position.
