Why don't pros have at least one really light ball?

Why is ball weight not a factor in ball arsenal the way that people have different golf clubs?
Wouldn't extra deflection be useful in some situations?

[striker12]

well it would but the heavy the ball is the more it will push the pins back and if u leave up splits it will help deflet the ball out of the back and back u onto the lane.

if you ahd a lighter ball and throw it fast fast it will not hit as hard as a heavy ball at 15mph and it will deflect alot but u can get the 7-10 split with a 6lb ball i have done is i spun the ball backwords and threw it down nice and gently and it hit the 10pin on the left side and it slid over to the 7pin but when it hit the 7pin it almsot never fell and it was not hard enoph to make it fall.

While it "might" be useful in some situations, you shouldn't because of Same reasons you shouldn't switch between conventional grip and fingertip balls.
The changes it would have on or that you would have to make to your delivery.

Different ball weights affects the gravitational pull thus the timing of the swing and release.

Bill, do you really want to go with this line of reasoning?

Throwing balls of different weights will mess up your timing, and once you have messed that up, it takes a looong time to get it right again.

Technically weight is determined by the force of gravity on a mass. In a free fall no force is measured because the force due to gravity is never felt. I know the science but for most people it would be beyond them. The way I stated it above was strictly to try to have it make sense for the masses.

Correct me if I'm wrong, Mike, but Bill, I think he was poking fun at what you said using a dirty mind. Either that, or I'm using the dirty mind. I found it funny. Taking the dirty mind out of the equation, it makes sense.

Jason, you're sick..but in a good way lol.
Knowing how technical Mr. White can get I figured he meant that the stated science was wrong.

The formula for the period of a pendulum (i.e. the timing) includes only the length (shoulder to hand) as a variable, the mass of the object has no effect on the timing.

Related is the test performed on the moon, where an astronaut dropped a hammer and a feather from the same height, and they both landed at the same time.

In this case, only you had a mental image of Bill's unbalanced balls.

Hahahaha... Well, not too surprising.. I'm the only one with the dirty mind here, I guess... lol.. Carry on...

If mass nor gravity have an effect on a pendulum, then why do they eventually quit swinging? Mass according to physics, is a quantity of matter as determined from it's weight. An object in motion tends to stay in motion but for how long? What unseen force over time causes that object to cease motion? Gravity. That one little thing the moon has very little of that Earth has in abundance. So on Earth, the mass does have an effect on timing. Otherwise clock makers would have been able to use any size, shape and weight object at the end of the pendulum to make grandfather clocks and their miniature clones.

The "unseen" force that causes an object to cease motion is called friction. Both in the "shoulder" and in the air.

The moon has 1/6th the gravity of the earth, the big difference is a lack of atmosphere. No air friction allowed the feather to fall at full acceleration, and keep up with the hammer.

A sky diver will accelerate towards the earth until reaching terminal velocity. That's when the force down due to gravity and the force up due to air friction match.

If you look at a grandfather clock there is usually a little adjuster knob at the bottom of the pendulum, it moves the weight up or down the arm effectively shortening or lengthening the "arm"
