913D2

Fred I

I have a 913D2 driver with Diamana Blue 62G Stiff shaft. It was built at 44.5 length and has a blue weight in sole. I recently cut it down to 43.5 and was wondering if the sole weight needs to be changed? What should the swing weight be at the new length and which color weight would get it back to where it was when it came from titleist?

    fred, I believe the stock weight should be a 9 grm.  ( red dot) The tech rep told me thurs., Titleist  builds their clubs to a D-1 or D-2 swing weight. Since you shortened the shaft a  half a inch less than std. you may be real close to standard. This is my opinion so take it for what it's worth.Also if  I'm wrong please correct me.

    So stock length is 44 inches and that would get a red dot..I had them cut down to 43.5 inches from factory so I assume they changed weight to blue dot ( 11g) to offset 0.5 inches less than stock. I now cut down myself to 43.5 so wondering if I need to put in a black dot weight which is 14g to get swing weight back to where it should be.

    My comments were incorrect...stock length would have been 45 inches and I had it cut to 44.5 from titliest..the club came with a blue dot weight....I then cut it down to 43.5 myself and my question is should the weight stay blue 11g or should it be increased by going to the 14g black dot weight?

    Fred,

    When we built the club at 44.5" we used the 11 gram blue weight to get the swing weight to around D1. At 43.5", which is 1.5" short of standard, the 14 gram weight would get you around a C7 swing weight. The 14 gram black weight is the heaviest weight we have. You could also experiment with using a lighter grip to try to get the swing weight up.

    Thanks

    Will, I have the stock velvet titleist grip on I now. what is an optional grip that would be lighter to increase the swingweight? Also should I experiment with lead tape? if so how much is recommended to get it to D1?

    Winn has a DriTac Wrap lite grip that will add 6 swing weight points. A good rule of thumb is 2 grams of weight on the head end will equate to about 1 swing weight point.

    Will, thanks...will try the Wrap lite grip and see how it feels...

    Will, one additional question..I have a cally driver that is cut down to 44 inches with a Boccieri Secret grip..I have had very good accuracy with that combination..If I went to a secret grip would that make my 913D2 light swingweight even lighter?

    That is not a grip we offer so I don't have any way of measuring it exactly. I looked that grip up and it seems to weigh about 92 grams. That is about 40 grams heavier than our stock grip. On the grip end of a club it takes about 4 grams to change 1 swing weight point. So if my math is correct, that grip would make your club approximately 10 swing weight points lighter than our standard grip. There are several factors that go in to swing weight (i.e. head weight, length, grip weight, tape and balance point of the shaft). I believe 10 swing weight points lighter is going to be close to what that grip would give you.
