The Razzle/Dazzle balls were reviewed in the April 2003 BTM.  They both had Super Flex covers, with the Dazzle being a solid.  BTM says that they are private label balls made by Columbia 300 for a group of distributors.  The ad in that issue said available exclusively at Ace Mitchell Bowlers Mart.

The Dazzle has a light bulb core with a flip block on the bottom (like bowldoc said) without the ceramic nugget.    The Razzle has a barrel shaped core with a large cap on top.  It was a 2 ball arsenal, a solid and pearl pair with Super Flex covers.  Both were rated very good on mediums, with the Dazzle playing better on the oilier side and the Razzle playing better on the drier side.
