Yes, within limits.

This is another way of saying what both Fred and Doug have said.

Right.

Exactly...no disagreement.

Right...again, no disagreement.

OK.

This is all spot on.

The main concern that I continue have in all of these discussions is 
that, setting aside for the moment all other considerations, it 
simply isn't always possible, let alone reasonable, to swap out 
hammers on a given instrument.  While I've done so hundreds of times, 
there have also been hundreds of times when the only option was to 
work with what was there.  It's pretty clear from the comments that 
have come up on this (and other) lists whenever these topics come up 
that a number of other technicians have had and/or are having the 
same experience.

Someone, I think it was Brent, noted that as people affiliated with 
institutional work (in whatever way that might be), in accepting that 
kind of work we take on a fiduciary responsibility to the institution 
to, insofar as we reasonably can, leave the inventory in better shape 
than we found it.  From the standpoint of institutional management 
(which is very different from that of the artist/technician), part of 
that means that the perceived fungible value of the inventory does 
not decrease anymore than is absolutely necessary; and, highly 
preferable, that it increases.  Obviously, there is (at least) a 
potential conflict of interest between these two positions.

FWIW, and acknowledging that opinions will vary wildly on this, I 
have direct knowledge of one situation at a major university in which 
the specific issue of using non-S&S hammers on S&S pianos not only 
cost the incumbent technician their job; but, far more importantly 
(due to the impact on the instructional program of the school), the 
piano shop was taken away, parts for repair and/or replacement had to 
be justified and ordered on a per-instrument basis for several years, 
and there was no budget for sub-contracting any of the 
work...everything that was done had to be done "in house" and on the 
clock...hard to do with over 400 programs to tune for each 
semester.  Eventually, everyone seems to have recovered, and the 
school is now on the road to becoming and "All Steinway" school; but 
there were a number of years before that recovery was possible to 
begin to implement.

My point in all of this is not that redesign and rebuilding along 
differing lines should not be encouraged, supported and 
developed...not at all.  Of course it should, otherwise piano design 
and construction will remain firmly rotting in the 19th 
Century.  However, if the only answer is to rethink and redesign 
every problem piano, then the vast majority of people who engage in 
institutional work stand to lose out on the kind of help and support 
they need to increase their own skills while providing improved 
support for the inventory for which they are responsible.

Most places simply do not have the budget or bandwidth to contemplate 
very much in the way of minor repairs, let alone major 
reconstruction.  Technicians often have to simply make do with 
whatever crumbs are left over from a table that is increasingly 
ill-supplied.  It doesn't matter that this is right or wrong.  What 
matters is that it is what it is; and the question is how we can all 
be of the most help to each other.

Indeed.

Best.
