I recently bought an old Great Big Bertha, 2 wood ( The Duece)
I love hitting it off the fairway or on tight holes as a driver… I love it
AS I’ve aged with a resulting loss of swing speed, launch angle and some amount of spin is needed to get the ball into enough trajectory for carry. I’m a few weeks before 76, my swing speed is 80 +/- so I have a 12 adjustable to 13 and 13.5. (Ping 425-G Max), When I could swing 110, I was 9-10. If the course is dry and I can get some roll, I’ll dial it down, sometimes to 11 but mostly 12 and if wet, I might take it to 13. With age, launch is needed.
