As we noted above, creating a dimple pattern is hard, which is why some manufacturers use the same pattern on multiple balls and why many overseas factories have just a few go-to patterns. That’s not ideal. In club fitting, we talk about optimal performance coming from the right balance between ball speed, launch angle and spin. Replaced launch angle with flight, and it’s effectively the same equation with a golf ball. Speed comes primarily from the core (firmness and size), spin is the result of the hard/soft relationship between layers, and the dimples provide the flight/trajectory. If the flight characteristics of the dimples are not optimized to work with the speed and spin properties of golf ball, the design is not maximizing its potential. In that’ respect, it’s a bit like not being able to alter launch angle in a club-fitting and it’s the reason why when golf companies put same dimples on balls with different performance specs, the pattern invariably performs better on one than the others.
