I apologize if this subject has already been discussed. I do not recall seeing it here previously.
Has anyone noticed that LaneMaster bowling balls are slightly smaller than those of other companies? My friend, who is a ball driller, called me last night and asked me that question. He happened to be weighing one of his older balls that he planned on using again. When he put the Pro Sect on it, he noticed space between the ball and the Pro Sect. He decided to check other LaneMaster balls that he has and it was the same for each of them.
I too am a part-time ball driller and have my own Pro Sect at home. While we were talking, I checked four or five of my LaneMaster balls. It was loose on each of them. I compared it too a few balls from other manufacturers and the Pro Sect fit snugly for each of them (even my daughter's old six pound ball).
This is not meant to be a bash at all. I have always liked LaneMaster equipment and still use them. We are just curious if this intentional. In the past, I have heard or read about studies or tests done comparing reaction or scorability of balls of varying diameter/circumference. I don't remember the details. I don't doubt that they are still within USBC specs.
Hopefully, someone from LaneMaster will comment.
