I have seen the skin used to good effect in conjunction with pins, where the pins were too loose a fit in linkage holes.
I have little against them unless they break too easily during handling of the instrument, I have nothing against the nylon pins, nor the PTFE tubes, providing they cannot fall out.
What I have used over metal pins when the hole is large enough, is 'spinnaker cloth', the super-tough, 0.05 mm thick, flexible, very finely woven fabric used for making spinnaker sails for the likes of Americas Cup yacht racing. (I just happen to live where some of the world's top sail makers work.)
This fabric is practically indestructible; it does not get holes worn through it as does goldbeaters skin, which in turn is far better than every polymer FILM that I have seen other technicians use. Its silencing action is excellent, I suppose partly because of its slight springiness.
FWIW, when I use goldbeaters, I cut it from a sheet made from two thicknesses, laminated together with contact adhesive, which itself seems to add to the toughness.
