What is different about the wippen?

Is it a sticker/rockerarm system. These aren't so bad once you get the hang
of 'em. The ones I have encountered display low friction, maybe from the lack
of the capstan to cushion rubbing.

If you opt of new parts, you can't be just a new parts installer. There are
geometry
issues to deal with. Improperly installed, the action will be a grave
disappointment.

All shanks are not equal, there are leverage issues which you need to be aware
of
for proper selection. You may even want to alter the leverage from the
original
because of newer, heavier hammers.

This is another function of the Renner USA Parts Kit.
Parts comparison/experimentation is paramount in selection.

Unless the wippens are beyond repair (which includes cost-effectiveness)
I would keep them. Consider the repetition springs to be fatigued, replace
them.
graphite and burnish jack and cradle, repin centers if necessary.
However on new parts, located and drill for capstan, install proper heel on
the
universal wippen unless a stock wip fits, the same flange screw holes can be
used.

Modernization has its advantages, you can tell I'm on the fence  :-)

Also you can tell I'm stalling because I have 5 pianos to tune today during
this
vacation period, four tomorrow and they're all done; whew.

I can't think of anything else so I'd better get to work, wish me luck,

Regards,
