The thread about which ball to use/favourite has got me thinking about what makes a ball hard or soft. I know they are ranked by compression, with the lower the number, the softer the ball. But how is compression measured and is one 80 ball the same as another manufactures? We all know there is no industry standard for stiffness of shaft, but is this the same for balls? Also is the scale of compression linear? By this I mean is the gap between a 80 and 85 ball the same as a 85 and a 90 ball?
