I have a ball that no one seems to know what it is. Zone Pro Burgundy Proactive Ball. Bought it in 1999, but the proshop forgot to give me the drilling/ball info sheet after they punched it. I LOVE THIS BALL!!! Got my first 300 and 700 with this ball. Now, I'm looking for something comparable, but no love so far. I have tried EboNOT (Matrix II and Vicious Attack) but they were both one trick ponies. The zone would work for me on any lane condition. Only place I have ever found on internet that mentions this ball is the PBA.com on their approved equipment list (its 9th up from bottom) saying it was approved 2/9/1999. if it helps, the serial number is AMU5741. Would love to know if someone has a copy of the drilling/ball info sheet that I could get!?!?
