To simplify the process, keep in mind the five categories of a golf ball to help consider which to use:
3. Driver Distance
Golf balls have a specific Feel, some are soft and some are harder. This is designed by the products that makeup a ball and how many layers the ball has. It is not terribly important to focus on the equation that leads to building a ball but what kind of ball feels good to an individual. Typically slower swing speed golfers, 75 miles per hour or less, prefer a softer ball to a hard ball and vice versa with faster swing speed golfers. For an example, Callaway has an ERC Soft Ball that feels softer to hit than a Chrome Soft or a Chrome Soft X. The Chrome Soft X would be considered a firmer ball but is just slightly soft. The Callaway Superhot ball would be a hard-firm ball because they are made for distance regardless of high or slow swing speeds.
Driver Distance and Compression go hand in hand because they both feed off of swing speed. Shorter driving distance links with lower compression of the ball, while faster swing speeds associate with higher compression. The shorter and lower combo is usually the beginner to average golfer type and would qualify for a softer ball. The longer-faster combo is related to more advanced golfer and that qualifies for a harder ball.
Last but not least the Price category. A dozen golf balls can range anywhere between $20.00 and $60.00, so find range that feels appropriate. Just because the more expensive ball would be well made, it might not work the way someone needs or wants it to work. Sometimes the inexpensive ball could be exactly what is needed. Do not let the ball options become overwhelming, remember the previous four categories and that picking a ball is mostly a personal choice.
