Played the " black " sleeve of balls with little fan fair. They seemed a little harder coming of the club face of the driver, irons and putter. Played in 15 mph wind conditions but didn't noticed any difference to my Pro V1's. The Prototype balls seemed to hold up better and didn't spin as well as my Pro V's.
Overall though I'd play the balls in the future and think most golfers would, depended on price!
Thanks for the opportunity,
Jim O
