So some of the 454 bats say they have HMF technology? Anyone know what that is? Do they still spiral? How to they differ from first 2013 line? What technology is new wse?
•HMF TECHNOLOGY - New Carbon Fiber material using High Modulus Fiber Technology. Fibers with smaller diameter allow more individual fibers to be woven together in the same amount of space resulting in amplified strength for greater performance and extended lifetime of the bat.
