I have a 910 D3 8.5 degree driver with the ORIGNAL Diamana Whiteboard 73x5ct flowerband shaft. The head has a red weight in the back. I was wondering if this would be the correct weight. because i have a 910 F 15 degree 3 wood with a 83x5ct flowerband shaft and i'm pretty certain that it has a green weight in. What should i do?
