I though I heard the titleist drivers stock swing weight is D3 but don’t quote me on that.

Thanks for your reply. They actually list a range of D3-D5 presumably because of the different stock shaft options and weights of those shafts. Titleist recommends surefit weights based on lengthening or shortening shaft but I cant find anything for added/ subtracted grip weight, which I think would be more common scenario. I'm trying to get my driver to feel like I'm not swinging a balloon on a string and more importantly where I can purchase the surefit weights.

From what I can tell adding 4g grip weight would decrease SW by one point. Adding 2g to the head increases SW by one point. If I were to add 15.5g in the grip then I would be decreasing the SW to from lets say for example D-4 to D-0. Therefore (and this is the part I'm not sure about) I should add 8g to the head to offset and neutralize the added grip weight and bring the club back to it's original SW of D-4. I would be adding to the overall weight of the club obviously but does anyone agree that this is the way to go? Has to be someone out there that has put on a heavier grip.

Try with the new grip first and see if you like it. One consideration is the difference in feel that the heavier grips cause. Adding more weight to the clubhead adds overall weight to the club, which is already happening with the heavier grip. Don't "chase" a certain swingweight by adding more overall static weight to the club. It might just end up plain too heavy between grip and added head weight. More weight on the head end makes the shaft play a touch softer as well.

If you like the grip on the driver, then it might make its way through the bag and if the lighter feel in the irons is ok with you. I stick to standard size grips and add layers of tape to build them up so as to not change the swingweight too much.

The weight of your grip does not really change the Swingweight the way the Swingweight scale was intended. It will certainly change the Swingweight reading you get on a Swingweight scale. Swingweight is meant as an approximation to MOI. The MOI does not change if you alter the weight of the grip. Nor does it change if you wear a watch, which has the same effect. I am not sure why you want a certain Swingweight. Are you trying to match your clubs so that you can have the same swing for all your clubs? That can only be achieved through BioMatch at rational-golf.com.

My long fingers fight themselves with a standard sized grip I do need a midsize grip but prefer the plus 4 in my woods. Midsize grips that taper work for me in my irons because I'm hitting shots of varying speeds and controlling face direction. In my woods I swing generally at one speed and leave my right hand out of it so the plus 4 helps (similar to a fat putter grip). I'm not trying to achieve a certain swing weight in my woods rather I tend to lose where the club is at the top if the head feels too light. Adding grip weight would only exaggerate this feeling so I thought adding one of the heavier surefit weights would alleviate this. I'm definitely not an expert on the subject though so I welcome any additional input.

The grip change effect on swing weight will be closer to 3 points so an additional 6 grams in head weight will suffice. If you are using the standard 12 weight the 16 gram weight will leave you just 2 grams light- I would give that a try and add lead weight if necessary.

Thanks. I currently have the standard weight red dot so that's about what I was thinking. Can't seem to find where the authentic weights are sold since Titleist doesn't sell them directly. Only ones I can find are OEM on eBay and they actually range from -4g to +8g so I may have to look into that.
