Grin... if I may...
<p>I think this is a case of talking sort of past each other.... Mike is,
I belive, saying "less inertia <i>relative</i> to putting leads out on
the end of the key"
<p>I dont think he is saying that more weight period results in less inertia...
that would be silly.... :)

<p>Once again let me say, It seems to me the heaver the key the more

the more
<br>EFFORT it will "SEEM" to be required to move it.

<p>Especially considering I asked.......
