Also, with the wide vs narrow bi-chord agraffes, what does the spacing width achieve?  I would think the wide might help for hitting only single string with the una-chorda pedal engaged. Assuming new bridges/ caps/ cap layuout, is there any other difference to choose between the two? Or does the wide assume large wrap sizes on large instruments (doesn't seem to be about core size, since the holes are all the same size)?
