Eguller I will throw out here the 1 ball that I've been playing all summer, and that is the Titleist Tru Feel. I bought a few dozen, same as new, off a fella on a golf site early summer. They are long, they feel great at impact(not mushy/not hard), they will spin, and they feel great putting. Very surprising find, imo. And even new, are only around $23/doz..
I do play other balls, don't get me wrong, but these are always in the bag/in the pocket/on the tee. Every round, at various times. If I had to play just 1 ball, for say a tournament, this would be it. Snobs will turn their noses up, of course. 😄
