Iam using a Kensington Trackball with 55mm ball. I tried to replace it with a polished stone ball and it doesnt work. Unfortunatly the stone ball is too heavy ( stoneball is apr. 250g , stock ball is about 100g) and it will persumly damage the ceramic guideway of the trackball.
My question is: Is there a way to interchange the original trackball and what kind (material) of ball should be work without damaging the trackball
