I am a 4 handicap player I am currently playing the Titleist 915 D2 10.5 deg driver with the Aldila 70 rogue stiff shaft. My actual carry on my 916 AP2 5 iron is 172 yds but my average driver distance is only averaging 232 yds including roll. My regular partners hit about the same iron length as me but are 15 to 20 yds longer on driver tee shots. I have used impact tape & am hitting the driver in a nice center group pattern so I am thinking that perhaps I need a different shaft perhaps a slightly higher launch angle with less backspin, any suggestions?
