Baldwin accujust hitch pins

[Bec and John]

Hi,

Someone I know complains the Baldwin hitch pins cause them to not stay 
in tune. I can't imagine the hitch pin would affect tuning in that way, 
but I wanted to ask what other technicians on the list think about 
that.

Any other comments about the hitch pins are welcome. I understand their 
purpose (isn't there another piano maker that uses a similar idea?), 
but I wasn't sure if it was actually useful in the real world.

Thanks.
