While stiffness was logically the apparent intent, it also 
effectively doubled the mass of the bridge, which would 
certainly affect sustain - likely more so than the added 
stiffness.

Or possibly just too heavy. Easy enough to find out if you 
have one getting a new soundboard and bridges anyway, or on 
the way to the dump. Cut through the under-bridge at the ribs 
and observe the tonal difference.
