I tested the new balls against the current pro v1, the 2005 pro v and the swoosh 20xi x. It was dry weather but the course was wet.
Ifound the new balls flew straighter with less spin but around the same height and about 5-7 yards further with my driver.
When i hit my long irons i found the ball flight was higher and they spun much more therefore stopping much faster!
The mid and short irons also had a higher ball flight with more spin.
Full wedge shots behaved the same with the same amount of spin and feel. I did notice a difference between the new balls and the 20xi, the Titleist have a nicer feel and are easier to control.
The only part of the new ball I didn't like is the feel off the putter. It feels a bit dead and lifeless.
Hope this helps in the development of the new Pro v1
