New New York Steinway shanks I suppose ?  We had a long discussion about
these just a bit back, seems they've gone off on a low friction kick.
They are supposed to be pertpetual motion machines by design as the
story goes.  I am with you tho, I do not like very low friction on this
point, and always opt for establishing as firm a hold as I can get. This
typically yeilds a 4-6 swingtest result.

If you want  Steinway shanks that are the old style with more usual
friction levels, you will have to get somebody in Europe to send you
some me thinks. Course you can always order shanks from someone other
then Steinway.
