I was lucky enough to receive a sleeve of 'test' pro v1 balls in the post this week.
Took the balls straight to the course this morning for the comparison, the weather had nose dived in the last week and was about 3-4 degree C and was quite breezy.
Started the test on the putting green and immediately found them to feel softer off the putter.
So then on to the course and a hit with the driver, seemed to launch a little higher for me with less spin (especially side spin) and no loss in distance considering the drop in temp, I didn't notice any softer feel but did notice though it seemed to be more stable in the wind.
Noticed a softer feel with the irons and seemed to gain a slight increase in distance even with a slight increase in launch and stable flight in wind.
The same shot stopping control you would expect from a pro v1 was evident on full shots. No great increase in spin(could be down to temp drop)
Short shots and chipping with this ball was the same as existing pro v1 just with the added soft feel, no great increase in spin here also maybe as above. Would be good to test again in warmer conditions.
All in all very incouraging early signs for the new ball and will be putting them straight in the bag once released.
