I have a Titleist 913D3 with a Fujikura Motore Speeder VC7.2 Tour Spec. I ordered this driver at a 44.75" length and a D4 swingweight. I wanted to shorten my driver by 1/2 an inch from the butt of the shaft. I have heard people say that every 1/2 an inch is about 2 or 3 swingweight points and that 1 swingweight point is 2 grams. I have an 11 gram blue weight on the driver head. So if I did cut down my driver length by 1/2 an inch, I wouldn't be able to return to at least a D3 swingweight without lead tape? I know that titleist's heaviest weight for the driver head is a 14g black dot weight, which will only bring back 1.5 points on swingweight. Also, will cutting down only 1/2" in length affect the flex? I've heard that 1/2" from the butt of the shaft shouldn't do any effect on shaft flex, but just curious to make sure. Thanks.
