<br>Here's an alternative way of looking at the same phenomenon,
<br>including a demonstration of what happens if you vary the location
of
<br>the lead:
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <a href="http:/real.uwaterloo.ca/~sbirkett/inertia.pdf">http://real.uwaterloo.ca/~sbirkett/inertia.pdf</a>
<p>Some years back when the list was still innocent we had a discussion
<br>of inertia. I recalI pointing out the discrepancy between static
<br>balance which depends on the distance to the fulcrum and inertia
<br>which depends on the square of the distance.
<p>Some might argue that the "assistance" provided by the lead in "soft"
<br>playing actually makes the action MORE difficult to control.
