I tell the story from a few years back, I was at a garage sale and they had a box with three sleeves of the Top Flight Z-Balata balls for $5. Had to take them as I used to play them. When we were on spring break with our kids, I took them to a par three course and I used the Z-balata balls. MAN now I remember why they were fun to play with all the spin you could get on them. During a regular round during the trip I took one out to play, for one hole. As fun as it was on the par 3 course to see the spin with wedges, the ball went no where with a regular shot, probably about only 80% of regular distance off the driver. Balls were probably 15years old or so.
