David, What do you mean by "the backside of the key"? Are you referring to the portion from the balance pin hole to the end of the keystick where the capstan sits? With reference to "uniform selection of the wood for the key blank", how do top or bottom stiffening plates affect this (such as John Hartmann has referred to)? I assume as long as the wood density is similar, the effect is minimal... as long as it's symmetrical around the fulcrum?
