In the practice area at my club here near Los Angeles there was a Volvik tour van and they were working with some Korean pro's, men and women. After watching them for a while one of the Volvik reps asked me about my game and the ball I used, and I told him I really like playing the Srixon Z Star. He asked me my swing speed, and not knowing, I just guessed it in the low to mid 90's. Hitting in the same setup that the other players were hitting I soon found out my REAL swing speed averaged 84mph.
They make the "Vista" which is their 4 piece tour ball, but he had me hit their "Crystal" and the "DS-77" against the Srixon Z Stars I had in my bag. Pretty eye-opening when I saw the results...and FELT the results. Ended up being fit with the "Crystal" which is a true 3-piece ball. Been playing them for about 3 weeks now and couldn't be more pleased. I knew you could get CLUBS fitted, but getting properly "fit" for a golf ball was something new...and LONG overdue!
I know the LPGA has a number of players using their balls, and now some of the Champions Tour players are using them too. What also surprised me was reading the results of "Independent Labs" testing that show the Volvik ball performing BETTER that even the Titleist balls. He told me that Volvik is stepping up their sponsorship of Web.Com players knowing that once they make it to the "Big Show" there will be more visibility for Volvik on the PGA tour.
I'm not trying to "convert" everyone, but if you get a chance give 'em a try...might just surprise you!
