Many thanks for the test balls..Played 3 rounds with each of red and black numbered balls. Both types produced excellent playability and touch. Extra length on both was a bonus for an elderly golfer with restricted movement and both provided good feel around the greens, although I gave slight preference to the reds in this respect. These balls undoubtedly look to maintain the Titleist market edge and I look forward to playing them on a more regular basis. Regards, Roy W.
