B= aldwin used an unproven material which failed later. However, they still did= not change the original design, which was to use the friction and durabilit= y of the butt skin on the keystroke, and its silencing capabilities on the r= eturn; and to use the angle of the jack/butt engagement for a positive energ= y transfer while allowing the (smooth, lubricated) jack tip to slip easily w= hile not under pressure (upon return). In addition to the lack of durability of the stick-ons, it could be said tha= t your method makes other design changes, such as a difference in the depth = of engagement of the jack, as well as a significant difference in the fricti= on upon its return. I would guess that the repair time didn't differ signifi= cantly from a return to the time-tested configuration. Shortcuts which might compromise the function are almost never cost-effectiv= e (or reputation-enhancing) in the long run, which is what we have the pleas= ure to deal with. There are things in piano design that can be improved, but= I want to make sure I have considered all the ramifications before I make a= change - not because of respect for the original designer, but because ther= e might indeed be a good reason that I just don't see. I have made a few tho= ughtless "improvements" which have come back to bite me in the  &n= bsp; . Best wishes for a durable repair, Bob Davis </HTML>
