- Iron Diamond

First Impressions
The Legends Iron Diamond presents itself as a special urethane ball with the Dynasty core, showing technical numbers of 2.590 RG and 0.045 differential at 15 pounds. As the only ball in the Bowlidex database with a urethane coverstock, it should hold a special place in the lineup. The Dynasty core delivers a very even, predictable arc, while the urethane surface allows for controlled reactions. The two-piece construction should provide additional drive through the pins compared to other urethane balls.
Comparison
In a direct comparison to the Storm Pitch Black, the Iron Diamond should turn in the better performance, even though it sits at a higher price point. Users report similarities to the Brunswick True Motion or the Global 900 Booyah in basic reaction, but with noticeably better carry than other urethane balls. For many, it counts as one of the best solid urethane balls on the market today. One comparison characterizes it as an "Iron Diamond on Steroids" with respect to newer urethane developments.
On the Lanes
The Iron Diamond should shine especially on dry lane conditions while still bringing enough power for pin carry. It has proven itself on the PBA's 33' Cheetah pattern as well as on short and medium sport patterns. On uneven house patterns it should also allow control over the head pin. Even players with a high track find enough flare for the desired ball motion with the right layout. Older players with lower speed in particular benefit from the controlled reaction — polished to 5000 grit, this produces higher scores. For sport conditions, it counts as indispensable in the bag.
