I've had my Rising Star since it came out and have never matched up better with a ball. Looking for another one. Have to trade a 607A, Fury Pearl , Reign and a Vital Sign all 15lbs. Vital Sign is drilled for a full roller. 607 has a span around 4 inches and Vital Sign and Fury around 4 1/4" Reign I believe is a little more. Prefer span closer to 4. Let me know if your interested. Thanks--Ken
