Hi David,
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.
I know an over generalization. <G>
My money is still going to be on the balance rail hole. The problem is far
more endemic than we think.
Regards Roger
