how to tell if a shaft is stiff or whippy?

Hi,
I am curious if there is a definite way to test a shaft if it is stiff or whippy?
Thanx

See how much you have to adjust your aim when you apply sidespin. When you put inside english on a cut shot, and you have to aim very thick on the object ball to make it, the cue is very whippy. Another way I test it is by using extreme follow, i.e. aiming as high on the cueball as you can without miscueing. Once you hit the CB, if you see your shaft vibrating like a doorstop, it's pretty whippy IMO.
 
I don't think this is rocket science.

Just try bending the shaft to the side. If it bends easily it is whippy, if it is hard to bend, then it is stiff.

A test could be developed by anchoring the shaft say 20" from the tip and hanging 5lb (or a plastic bag with 10 balls in it) say 1" from the tip. Then just measure how far the tip bends down. This way would could develop a standard for comparison.

Perhaps someone knows of a standard industry test?
 
Hold the cue with your butt hand and strike your joint and watch the tip of the shaft vibrate. Do the same thing with a broomstick - notice the difference.

Shoot a spot shot with english using a broomstick.

A player had a 6.0" brass rod inserted into the shaft behind the tip and told me to shoot a normal spot shot with english - I wasn't even close - couldn't hit the ball. How much the stiffness or added weight added to the cueball veering of line I don't know.
 
Don't mix the concepts of stiffness and deflection. More mass in the tip area, more deflection. Doesn't have much to do with stiffness. Playing with a steel rod would be impossible, because there would be too much deflection.
