<DIV><FONT face=Arial size=2>David hits the nail on the head. As inertia is
defined as mass x velocity, there is an equal trade off in the weight verse the
position of leads. So we should be talking about the limit of acceptable FW. In
my experience if the lowest key starts with front weight in the mid-forties
(grams) where the FW matches the strike weight in its curve, there will be that
inertia dampening effect (pardon the Star Trek jargon).</FONT></DIV>

<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">With respect to the
question of how many leads it has as much to do with position as number and
really boils down to the overall front weight of the keys. If there are
a lot of leads or if they are all pushed way forward on the key, a high
measured front weight can introduce inertial problems such that even if the
static weigh-off is light the dynamic performance can suffer from a feeling of
sluggishess. That’s why overcoming weight problems by simply adding more
lead can be counterproductive. How many leads and their position in the
key will give you a quick indication if there might be a problem in this
area. </SPAN></FONT></P>

really is it simple - how many leads? My recollection from Stanwood classes
that I have attended is that ideally an action will have three - two - one -
zero lead in keys running from bass to treble. The implication is that if more
lead is required, then maybe action geometry needs to be looked at. I don't
know that four leads is any death pronouncement, but it may be a reason to
look closely at many factors.</SPAN></FONT></P></DIV>
