Any strategy that can meaningfully affect performance that, once it’s attended to, doesn’t require any conscious effort from you, is low-hanging fruit. If the specs of your clubs don’t match up, or even conflict, with your ball flight goals, you may be having to work harder than necessary.
Example: If your tendency is to launch the ball too high with your driver, but you are using a high launch shaft and a low centre of gravity head, you will be bleeding yards.
Example: If the bounce on your sand wedge doesn’t match the bunkers of your home course, reliable contact could be compromised. A joined-up coaching/fitting hybrid approach allows you to match things up.
Anti-learning - Either no custom fitting, or no clarity of ball flight/roll goals to be fitted against.
What is good?
