I bet every tip on earth will be about the same hardness within a month after installation.
I have a durometer and it means basically nothing. I tried to come up with a way to measure accurately the hardness of tips.
Here is my theory on the relatively recent, within the last few years, obsession with tip hardness;
I believe that whenever a player puts a tip on their cue they want a certain feel. If they get that feeling/hit then they basically play into the tip. Every tip will reach what is called a maximum compression and when depends only on how many shots in what period of time are taken as well as how hard those shots are on average. So while the tip is being compressed the player is comfortable with the tip and is getting used to it.
Anyway, I think that knowing whether a tip is hard, soft or medium does offer comfort but is not really a great indicator of how a particular tip will "play". Even so, I prefer an Instroke 11 layered soft. ;-))
