I recently bought fitted ap1's 4-pw xp r300 shaft last summer. I injured my left shoulder about 2 years ago. At the time I thought I was healed but I wasn't. I have been working with my physical therapist on strengthen my whole body. I would think my swing speed might change. I am going to be fitted for the new 915f and 915h this spring. I have been thinking about checking my iron swing again. I love the clubs, I was wonder if it was worth replacing the shaft on them. That's if my speed has changed. Anyways how much would it be? I would go through Titleist to have the work done.
Thanks
