I put them into play last Friday at our TT event and loved how it played. I received the test balls with the Red Numbers and noticed they were longer and more durable. I usually play the PRO V1 and another TT member hinted these may be the new version, not sure though.
There is a hole where we played where I hit my 3 wood all the time off the tee and there is a ravine about 290 -300 yards out. Usually I am 20 -25 yards short, using the test ball I ended up in the ravine. Bad for my score card but a great indication of how much longer these balls appear be.
Also on hole trying to cut the ball around the dog leg I hit square on the cart path and the ball showed hardly a nick, no question on durability.
Each of the two bunker shot's I had I got to within 3 - 4 feet so I would say performance tee to green was excellent.
Gotta give these prototype's an A+ !!
