If G 10 epoxy is harder than the cue ball would it cause damage? It is a fact that G 10 is one of the most popular materials made famous by let's see, well I do not want to point any fingers but a few come to mind. It is almost unbreakable on the shaft of a cue and will create more mph than a softer material. The question that has never been tested is, can a harder material than the cue ball cause damage? Can a softer material cause damage, has not been tested either. Is there any scientists out there that can answer these most important questions?
