Hi - played yesterday with the test golf balls sent and was somewhat disappointed. Started the round using Pro V1, to get into my regular swing and feel, then changed to the 'Test' ball. Found that driving distance was slightly shorter than Pro V1, and that the Test ball felt awful off the face of the driver - felt very much like hitting a cheap 'distance' ball, like hitting a pebble. Mid-irons (5 through 9) also felt very chunky off the clubface, though distance tended to be slightly longer than Pro V1. Short iron distances were very much as for the Pro V1, but with a little less control. However, I did enjoy putting with the Test ball - came off the face of the (Zebra) putter consistently, to enable good distance judgement. On yesterday's experience, not a ball I would put in my bag.
