Good morning. I have a 910 D3 with 73 gram diamana whiteboard. I also have midesize lampkin grip on it. I was having trouble with not being able to feel the head in my swing. we check and it has a D0 swing weight......we put lead tape on it but is there any other option to bring back up to standard D3 swingweight? Also would the grip/shaft combo cause this? thank you Jim Hoffman
