10.0pt;font-family:Arial;color:navy'>My comments were really on a different
thread addressing what constitutes too much lead, but trying to draw a
relationship between high upweight and amount of lead is dubious. There are
many examples of high upweights and overleading as friction within the system
is the more likely cause of low upweights than too much lead. I do agree
that the balance rail hole, or angle of the balance rail pin (to much rearward
inclination), or early damper pick up are all good possibilities. But
since those were mentioned prior to my suggestion to examine the amount of
lead, I didn’t feel it necessary to restate them. </span></font></p>

style='font-size:12.0pt'>Hi David,<br>
With an average up weight of 28gms, I would seriously doubt there is too
much lead in the keys. Too much lead tends to give you an up weight of
50% or less.<br>
I know an over generalization. <G><br>
My money is still going to be on the balance rail hole. The problem is
far more endemic than we think.<br>

style='font-size:10.0pt;font-family:Arial;color:navy'>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>
