Dear Titleist,
May I make a tech suggestion. Rather than having the smaller head 913f with the weight in the back, and the larger 913Fd with the weight in the front, could you think about this idea: Let the player choose the head size, then have 2 weight ports on the bottom of both clubs, one near the face, and one near the back. One of the plugs will be a near weightless plug, and the other will be the standard 7,9,11 g etc plug. That way, the player can choose the head size they want, and then vary the spin, launch, and control by moving the weight where desired. I currently game a 913d2, 913fd, 913h 17, and 913h 21. I love them, but was having issues with the fairway wood off the turf. I know, I could get the 913f (I had the 910f), but I wanted the bigger face. So what did I do?? I removed the weight plug near the face, and have added lead tape on the sole, covering the hole, and concentrating most of the weight near the rear (like the 913f). And it is a thing of beauty!!!!!!!!!! Please consider changing the design of the sole plate to accomodate 2 weight plugs.
