John and others,

I looked at your picture of the added top plates, and have a question. Part 
of the stiffness comes from the taller beam and part from the species. Would 
it do any good to rout out part of the top of the key and replace it with a 
stiffer species, say maple, or would that be insignificant if the key height 
remained the same? Same goes for shoes.
