2012 RockeTech Fast Pitch Softball Bat (-9) From Anderson

Product Review

Designed specifically for the diamond sports enthusiast Ð and unlike composites that gradually rise to a short-lived maximum potential - Anderson's design and use of high-performance materials and components, will deliver superior performance and will maintain a solid feel throughout product life.

Before Anderson's PowerArch™ design, there were two basic schools of thought for a multi-wall interface configuration. The first was that bat walls are loosely fit with a space that is filled with a viscous medium so the walls flex consecutively É or one and then (or into) the other. The second was that bat walls would fit snugly, and have constant contact so the walls would flex simultaneously.

Each of these has its advantages and disadvantages. The outside shell/inside sleeve with a space had better overall performance, but was more susceptible to denting. The outside sleeve/inside shell with constant contact was a little more durable, but traded overall performance. Both designs had two separate walls of equal thickness. The trade-off is reasonable because the performance/durability differences were relatively small but certainly measurable.

The Anderson PowerArch™ combined the two schools of thought. By having a series of opposing arches where there is intermittent constant contact and alternating separation between walls, it allows the walls to flex both independently and concurrently. It allows for a differentiation in wall thicknesses that improves the shortc
