I would be suspicious of any claims of using "100 Year old elastomers" as polymer chemistry had its start circa WWII, and the aging properties of natural rubber is not so good.
MC phono cartridge lifespan (when not using)
I have bought a new Benz Wood SL and a few weeks after I have received a new Benz Glider as a gift. I have the Benz Wood mounted on my Ittok and really like the sound....I’d like to know if it is wise the keep a Glider as a spare/replacement when the Wood is worn out....That could be in 5 years or more.....so my question is really....will the Glider sound as it should in 5-10 years or will some parts deteriorate even when not using.... Suspension parts or oxidize coils or any other parts....Or should I simply sell it and buy something else when needed.....I know the Wood sound a bit better but I could live with the Glider as I had one before and loved it....
