Not sure if anyone remembers the Wilson 50/50 (50 compression ball) several years back... had to be mid-2000's.
Anyway, someone gave me a sleeve of these and I played them one day. I shot 75 that day. Couldn't have been more than $19.99/doz maybe? Maybe it was a good day of ball striking and a good day of putting, whatever. But I think it just reinforces the point that if you're swinging well, thinking well and putting well - the type of ball being used ain't gonna equate to an enormous difference in scores.
I'm sure just about everyone remembers the Precept Laddie... same thing. Low-compression, and I most always used them in the offseason when the temps dropped and the leaves were falling.
I prefer a softer-feeling ball for sure, but again - when it comes to tournament play I most always revert back to the type of ball that has performed well for me in the past. When I'm not playing tournaments, I tend to use whatever stock I have in the basement.
For the money though, the Srixon Z-star 3-piece is a very good, durable ball that is very close in performance with the more premium ones. They're roughly $29.99/dozen. They're just as good as anything else I play.
