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?

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.
