I have only played 9 holes with the balls sent to me so far. I tested these along side Pro V1x. I'm pretty sure they were just the newer model. I'm a high handicap so I just played like I normally would. First off the driver I think I was longer but not by much with prototype ball. Next on my mid irons I didn't notice a huge difference. Inside 100 yards I noticed a much better shot on green. My Pro V1x Ball was consistently 8-10 paces from my divot. That really isn't bad in my opinion. The greatness of the new Ball was the bite. Every shot was within 3 paces of the divot. I have only played 9 holes but shot at least twice on each hole. The bite on shots inside of 100 yards at this point will allow me to attacka pun like never before. More to come once I get off overtime.
