Hi I too tryedGraf Graf. Shafts in a set of ap1s 716. I didn't care for the feel as I didn't get fit just ordered them but I went to a cerf. Titleist fitter and I have now 716 s in Nippon 850 shafts in r flex . The improvement is a lot over the feel of the Graf. And the distance is very good very repeatable distance. I'm 74 could not be happier with the switch to these shafts contact Titleist they can help.

I'm 74 with a swing speed of 75. I got my new 716 Ap1's with the KuroKage A flex shaft last fall. Played a couple of rounds up north, then quite a few in Florida. Loved the combination and FEEL.

I am 70 years old and just received my Ap1 716 with the kurage 65 tini shafts regular flex. I was fitted at a Titleist day @ St. Andrews Valley. This is my first set of irons with a graphite shaft. I have hit them at the range for 2 days now and have found that the ball goes further straighter and higher than my png I 25's with steel shafts. These shafts feel great and would highly recommend these shafts. There is also a great feel of the club head throughout my swing. Thanks to Titleist for putting together a great set of irons
