The Vexed features an RG of 2.498, an Intermediate Differential of 0.012, and a total Differential of 0.036, creating a 3:1 Differential ratio—considered the ideal balance for this type of performance design. In terms of drilling dynamics, the Vexed continues where the Evil Eye left off. The Evil Eye’s Intermediate Differential ranged from 0.007 to 0.023, while the Vexed expands that range slightly, running from 0.008 up to 0.029.
Like the Evil Eye, drilling recommendations for the Vexed revolve around the position of the thumb hole and its interaction with the core. Both balls rely on drilling into the core protrusion to influence motion and overall reaction shape. The key difference is that the Vexed core is engineered to create more motion downlane, making it an excellent companion piece to the Evil Eye.
During testing, bowlers consistently noticed more overall hook and a quicker response to friction with the Vexed. The combination of its stronger core and the upgraded HK22C+ coverstock produced a sharper backend motion, leading testers to conclude that the Vexed pairs perfectly with the Evil Eye as a powerful one-two combination.
Here's what Radical has to say about the Vexed:
The Vexed has an RG of 2.498, an Intermediate Differential of 0.012, and a total differential of 0.036, resulting in a Differential ratio of 3 to 1. This is the sweet spot for Differential ratios. The Vexed’s drilling numbers pick up where the Evil Eye’s left off. The Evil Eye’s Intermediate Differential ranged from a low of 0.007 to a high of 0.023, while the Vexed ranges from a low of 0.008 to a high of 0.029. The drilling instructions for the Vexed are based on the same concept as the Evil Eye, taking into account where the thumb hole is placed. Both balls use drilling into the core protrusion to dictate performance; the difference being that the Vexed core allows for more motion down lane, making it the perfect complement to the Evil Eye. When our testers compared Vexed to the Evil Eye, they found an increase in overall hook and a sharper backend motion due to the stronger core and upgraded HK22C+ cover. They all agreed that the Vexed and the Evil Eye are a perfect one-two punch.
