GH1 voicing revisited

I would like to second this motion!  That is exactly what I have found, too.
Although, once it's in tune, the tone quality remains poor in that section.
The information I have found most valuable has been that the tension in that
section drops drastically.  I can only assume that lower tension means the
soundboard and bridge are free to flex more as the humidity changes, especially
at the end of the 'hockey stick'!  Therefore, the best fix to the (old) GH1
grands would have to be the more involved re-scaling of the problematic five or
six notes, and not just voicing.

Randy Potter originally posted the info about this retrofit.  Has anyone else
done this?  I would be interested to know if the results are worth it (better
tone AND tuning stability), before suggesting it to a customer.
