I am looking to get a T250 U 4 Iron to bridge the gap between my T250 5 Iron ½" Long Standard lie True temper AMT Silver Stiff shaft and my GTS 21° 7Wood Mitsubishi 1K Blue 65 Stiff shaft . I have tested the stock shaft Hzrdus Black Gen 5 80HY 6.0 in the T250U but wondering whether a Mitsubishi 1K Blue 75HY would be better suited as I love the feel of these in my new GTS Fairway woods
