 I don't know. Good question.

The clear tubing looks good and clean, I'd be less incline
to use black neoprene. Also, although the material was flexible
it was resilient enough to grip the shank tightly, It was easy
and cheap to work with.

No glue, nice tight wrap.

Easily removable.

I had heard about the Yamaha clip version but could not get any.
I understood Yamaha was no longer supplying them.
So I came up with this idea on my own as a substitute,
searching for something easy and unobtrusive to add to the
shank. Clear tubing wrap seems too easy not to try.
I was using 1.5 inch segments on the shank.

Apparently Ernie Juhn  was on to this with an
upright piano version of this solution.
I was dealing with a grand action, and wrapping the
shank. He was dealing with an upright action and wrapping
the catcher.

record...

U1 action too light for customer.
Yamaha sells little "clip on "things" which go on the catcher and make the
action "heavier" for those who feel that they want it to be (heavier).
They call them touch weight adjusters and they can be moved forward or back
on the catcher dowel and that makes them adjustable.
A cheaper,  just as good and my own idea is as follows:
Get a piece of vinyl tubing 6/16 od - 3/16 id. (very cheap in hardware
store).
Cut 88 about 1/2  inch long pieces and with a single edge razor blade slit
them open (easily done by standing them up on end).
Finally slip them over the catcher dowels of the action.
It is cheap, fast and above all - reversible in minutes.
