Jason Day used the Kuro Kage TiNi to win in a playoff at Torrey Pines on Sunday. Jason is one of 15 of the top 25 PGA Tour players that have Mitsubishi Rayon Shafts in their bags. We tested the Kuro Kage TiNi a little over a year ago when it was in its prototype stage and were impressed with its stability and low spin (See our post here). Mitsubishi Rayon has a wide variety of iron, hybrid and wood shafts to literally fit every style of golfer. We know…we test them and have them all in our shaft research database!
