Just received my GD ADI 6 custom shaft from Titleist. Switched out the stock shaft on my D2 in seconds that then hit the course (range is still closed for winter). We open with a 390 yard par 4 at my home course and never been inside 100 yards before. Launched the first drive with 85 yards.   This shaft is long... You will see extra height but its controllable with the settings. Can see why TW switched.
