I have a general question and to BrunsBob in particular. Why don't bowlers like Del Ballard, Pete Weber and yourself, whose strong releases and relatively slower speed dominated the Urethane Era, return to using urethane equipment? Is the disadvantage so great that they couldn't compete against the resin/particle bombs of today? Are the cores THAT much stronger than were found in the stronger balls of the urethane era that the difference in carry is that much? Are the lane conditions THAT much different? There are a lot of days that I wish that I hadn't given away my Ultimate Weapon, especially when the gutter is open for business. Can a Blue Hammer compete against the Infernos of today?
