There’s a point in your bag where your consistency of ball striking and accuracy start to break down or disappear entirely.
We probably accept that Tour caddies are better at reading Putts than most of us. There’s an opinion that they’re masters of some “dark art” of green reading.
When you crouch down behind the ball or stand up and walk around the Putt, what are you really looking at? Do you have a process to read the green? Does your local knowledge suffice?
So why have club lengths got longer (and lofts stronger)? One argument is that the manufacturers know we love to buy extra distance.
