I picked up one of these overseas hidden treasures on ebay a few days back and it arrived with thet following specs.
15 lbs 5 oz, 2 oz top weight 2 inch pin.
well i found little info on this ball other than it has the core in a core construction and a cover called Muscle EX. The ball is a pearl, so this is a pearl particle ball.
Found the ball on BBR.com
http://www.bowlingballreviews.com/ball.asp?ballid=2462Ball looks really nice.
I placed a 4 1/2 x 3 3/8 with a balance hole below my thumb.
This drilling is also known as RICO1 on the brunswick boards.
The ball reaction got stronger as the more i used it, on fresh hard arcing with lots of punch. carry was better than average. on carrydown the ball struggled. Played on mediums with good backends. This ball was about 4 boards weaker than a drive drilled 5 x 5 with pin below middle finger.
so far i like it.
