I only comment on the ball because I have some experience playing current tour balls and older tour and distance balls. The modern driver hits the ball farther and the modern ball goes straighter. It's a deadly combination. I don't recall hitting the ball > 325 yards on any drives before 2000. A drive over 300 was a rarity. Surely at 45 I can't be that much more fit than I was at 25, can I?
