Test Ball: 15 lb., pin 3-1/4", drilled with pin 5" from PAP; CG kicked right, approx. 3/4 oz. positive side weight, no X-hole (yet).
BOWLER: RH, 'rotationally-challenged', medium ball-speed.
THIS, is an amazing ball.
I have tried it on several different patterns in several houses, both wood and synthetic. The results are uniformly good. The only drawback I have found, and it's manageable, is that if the midlanes are spotty, the ball can move too early; but this is easily adjusted by a small move left.
The ball gets through the heads easily and cleanly,whether they're freshly oiled or fried to a golden crisp. It gets plenty of distance down-lane, except (as noted) when it hits dry too early. And the move is a STRONG, arcing hook, not a 'snap' but not too far short of one. The thing is, I've been able to do almost ANYTHING with this ball-- I've pointed it to the pocket on fresh, long patterns with no problems of overreaction or corner-pins; I've played down the boards and arced it to the pocket flawlessly; I've played deeper, TIGHT lines, very direct, and it handles this beautifully; and I've stood left and swung it out and it bends right on back with the best of 'em. I've even shot 10-pins with it! It's almost an ALL-PURPOSE bowling ball.
And the HIT!! This ball hits and carries like Sherman took Georgia. The reaction is a strong, continuous arc, very controllable, and it REALLY hits.
Oh, yes, one more thing: A decade ago, another company came out with a coverstock material (beginning with "A"), and advertised that it "would not track up like reactive resin". They were right-- it tracked up THREE TIMES FASTER than reactive resin. Now, Brunswick claims this ball is much more durable than conventional resin. THEY ARE CORRECT. I have about 60 games on mine, and I have yet to be able to discern ANY tracking on it at all. NOT A SCRATCH. Amazing.
OVERALL: AT LEAST a 9. Absolutely amazing ball. A MUST-HAVE weapon. Might be the ONLY ball you'll need, apart from perhaps some 'special-effects' stuff for really radical conditions. So far, I haven't found a condition I couldn't use it on and be comfortable.
