HI Looking for some help with shaft fitting. I am looking at 716 AP2 irons for play this season. I am currently playing a nippon pro stiff shaft that I believe is 100g. My current ball flight is very high and I would like a more penetrating trajectory. I have a quick transition and was hoping a slightly heavier shaft would lead to better transition at the top, more penetrating ball flight. My pro is suggesting an Xstiff shaft. Driver swing speed is 105 and I am 6'2" tall so I will be getting the clubs .5" over standard length. thanks for any input
