I recently purchased the Srixon Z-star XV Tour yellow golf balls to see what all the buzz was about. My product arrived in a timely manner, as have all my purchases from Amazon. I am a 10 handicap, I only play once a week, I have played mostly Pro V1 and Pro V1x in the past. I have played Taylormade, Bridgestone and Calloways. The Srixon was close to all of these other balls as far as length of the tee. What impressed me most was around the greens, great feel, nice bite. I have played many shots from 100 yds and in with the one hop, stop bite. Getting a bit older, I did like the yellow color, easy to track and to find. I am not going as far as to say this is my new favorite ball, but performs well.
