The PROline IAC is a less common composition which offers sharpness on contact from it’s stiffer Koto wood top layer, while offering a superb balance with its inner layer carbon fiber. With KL-c fiber close to the core, the blade offers more forgiveness for even the most offensive shots, creating a unique feel of a longer dwell time – even with a stiffer top layer. The PROline IAC is a great option for players who need a little added cushioning and control from the classic Koto and Outer Layer carbon compositions.
