Recently, I have noticed unacceptable variations in hardness within the same box of tips (triangle, LePro and Tiger). I would like to test the hardness of the current tip on a cue and be able to put on a harder or softer tip to the player's preference. It looks like a durometer (hardness tester) is going to be $300 plus, but it may be worth it to satisfy customers. Does anyone know of a reliable brand that is cheaper? Tigers test in the 95-99 range on the A scale. Should I look for a D scale? Any knowledgable responses are appreciated.
