I don't know really what to say about this ball. We had a love/hate relationship. This is one of the BEST balls ever made!!! But the cover is soooooooo bad!!!! I just can't say how horrible it is! After 10 games or so, I could see a difference in the recovery on the backend. Then you could go week by week and watch it die. I would have to dull it with liquid sandpaper and a scotch brite every week. Every other week,I would take it to the pro shop and put it in the rejuvenator (oven)and that seemed to perk it up for a week or too. I don't even think that resurfacing it would have helped. I finally bagged it, and got a Blade Particle. Great Ball there!! But the 4-D for the price I got it for on ebay (59.00) I couldn't pass it up. For 2 or 3 months of constant extreme maintenance it was a great ball. Shot my best game (290) with it and my best series (736). But it is dead now. I have never seen a cover like it. Hated to see it go.
