At 65, I like the idea of the of new technology in golf balls for distance maintaining spin control around the greens. As the MOI in drivers has maxed out several years ago I believe that after being fitted for shafts this is most helpful. I purchased Maxfli GC & Oncore Avent 55 after reading about them on this site. So I now save considerable amount of money not purchasing Pro V's anymore and getting same results!
