I tried the KBS Max HL Driver Shaft because I had recently lost significant swing speed. I had tried a variety of light weight shafts - however, I continued to have drivers drop from their apex too quickly. The KBS Max HL, once I dialed it in in terms of swing adjustments - it really needs a smooth swing - my drives have begun to lengthen out with no more dropping from the sky as before. I would strongly recommend this driver - it is especially helpful that it is based on swing speed and not flex.
