The Flux™ core in the original Thrill™ is replaced in the Top Thrill™ with a modified Halogen™ core previously found in higher performance Motiv® bowling balls. The new Halogen™ V2 has a slightly higher RG than the original with a lower differential. The Halogen™ V2 is uniquely suited for dry lanes, but with a strong enough core to allow for more angles of play and significantly more versatility in drilling options.
