I have a 21 degree 910f with a Bassar W 55 shaft in it. I also have a orange Diamana shaft that I had from my 910 3 wood, I currently have an upgraded shaft in it now. My question is if I have the Diamana cut down to the length for my 7 wood do I need to change the weight on the bottom of the club to keep the swing weight the same? Thanks in advance.
