During demo days, they bring in several models of balls, in several different weights for people to try out.
The demo balls are drilled with several different spans (they might not be a perfect fit ,but should be close.) and use interchangeable thumb and finger grips in the hole.
So when you come in you get fitted for your grips, you pick out the ball you want to try, with a span close to yours. Put the grips in and try it, when your done. You take it back, take the grips out and try another one.
If you find one you like, you buy one and have it drilled to fit you.
example:
Ebonite International hosts Demo Days events around the country, providing the bowling public an opportunity to try balls from Ebonite, Hammer, Track and Columbia 300 brands before buying.
