The balls are recommended for training in the garden a lot. Even if you meet clean fly the balls too far (10-20 meters), you score nothing broken and hurt anyone. Sure, you can not read too much from the trajectory of these balls. But you could tell if you have made reasonably and in particular to allow the clean sweep to be trained. As an accessory I will possibly even buy a hitting mat to the preserves in the long run the lawn ... ;-) A note: The balls are more suitable for training with the iron. The Driver is dented balls.
