I’m now 84, age-appropriately decrepit plus a few other baddies. Hcp never lower than about 15, now more like 22. My swing speed’s way down, probably under 72mph, so I have whippy shafts on all my clubs. When I started playing, over 70 years ago, woods were mostly all persimmon, and I’ve kept most of them. I began using metal woods years ago, and they were fine and long, but for some reason I began to lose control with them - often slicing, the occasional duck hook. A couple of years ago I tried my persimmons again, and made a useful discovery. While the metal woods were longer, I often ended up in the rough, jungle, or worse, and my Hcp soared. With the persimmons (1, 3, 5) I’m shorter, but much more accurate, almost always stay on the short grass, which has improved my Hcp - I even have the occasional bogey round (gross). I have the impression that persimmons have much more effective bulge and roll than the metals (which, however, have the trampoline effect providing length), and that’s a great help.
Altogether, I wish I’d had the idea years ago, and I can highly recommend persimmons (with whippy shafts) nor only for older golfers, but they’d probably be most useful for most mid-handicappers, too.
