In a reed organ, the coupler not quite doubles the down 
weight, since the second pallet valve spring resistance and 
coupler friction is at a significant mechanical leverage 
advantage on the coupled note. You wouldn't get that luxury 
with a piano action, since the key dip to hammer blow ratio is 
less forgiving, assuming the top key row plays two notes an 
octave apart. Does it work that way, or does the top manual 
just play the octave above?
