I'm 71 and only hit my drives about 170 yards, at best. There's three balls that I have been playing recently to figure out which one works best for me. They are the Srixon Soft Feel, Mizuno's RB 566 and Snell's Prime 2.0. They're all similar, but for now I'm sticking to the Prime 2.0. It has a urethane cover and behaves better for shots into the green.
