Hi. I was recently gifted a 915 D2 driver 9.5 deg loft. The shaft was a regular Blur one inch longer than standard. I am a 5 handicap but could not control the club so I swapped out the shaft for a Diamana S+ 60 regular standard length. My shape is now a slight push as opposed to the draw with my previous drivers. I notice that the head weight is the green 7gm. Should I change the head weight to compensate for the shaft change? Thanks for your assistance.
