Currently I have the AWT shafts that weigh 96g/standard length in my G10's. They swingweight to D0. I'm planning on re-shafting with DG that weigh 130gr/plus 1/2" length.Using the same grip, what will I expect the swingweight to end up at? My rookie estimate is D6.7? Right or wrong?

If right, what would be the best way to get it to D2? Add weight to the butt? How?

Also, would adding 4 grams (2 sw pts right?) of lead tape above the Custom Tuning Port as high up on the back of the clubhead as possible, lower the trajectory enough to notice?

Thanks for the help.

130-96 grams = a change of 34 grams

most sources quote 9 grams of shaft weight changes 1 SW point so: 34 / 9 = 3.77 or D3.77 If you don't want to shorten the clubs, then you would need to add grip weight or back weight to get to D2. The numbers I've seen claim 5 grams increase in grip would bring the club down 1 point. 5 x 1.77 = 8.85 grams should do. 4 grams of lead tape will do nothing to change trajectory. Some will tell you it will. You need 30 + grams to change center of gravity. 4 grams might change the ball flight, but only because it makes the golfer feel and thus swing the club differently. Good luck, and realize I'm no club builder, just a math nut.

We don't have "math nuts" down here! LOL. Thanks for the confirmation.

Damn Damn Damn, I missed the 1/2" over that would make it D6.77. I totally flaked on that one. 3 more SWs for the 1/2" over.

Well neither one of us know what we are doing b/c I put the DGs300 in my Ping G10 irons last night and took them to check the SW this morning and was baffled. With the 52 gr grip, they balanced out at C8!!!!!! This was at standard length. At first I thought maybe the shafts were SL300's and not DGS300's, but I confirmed that. I guess when you think about it, it makes sense that the heavier shaft would decrease the SW. It all depends on the where the balance point is. Whatever, now I have to jam a bunch of lead tape on the head.

    • Nah, man. People have been testing clubs like this for decades at this point. Even 35 years. @M2R, are you AskGolfNut? If you're not, you seem to have fully bought into the cult or something. So many links to so many videos… Here's an issue, too: - A drop of 0.06 is a drop with a 90 MPH 7I having a ball speed of 117 and dropping it to 111.6, which is going to be nearly 15 yards, which is far more than what a "3% distance loss" indicates (and is even more than a 4.6% distance loss). - You're okay using a percentage with small numbers and saying "they're close" and "1.3 to 1.24 is only 4.6%," but then you excuse the massive 53% difference that going from 3% to 4.6% represents. That's a hell of an error! - That guy in the Elite video is swinging his 7I at 70 MPH. C'mon. My 5' tall daughter swings hers faster than that.
    • Yea but that is sort of my quandary, I sometimes see posts where people causally say this club is more forgiving, a little more forgiving, less forgiving, ad nauseum. But what the heck are they really quantifying? The proclamation of something as fact is not authoritative, even less so as I don't know what the basis for that statement is. For my entire golfing experience, I thought of forgiveness as how much distance front to back is lost hitting the face in non-optimal locations. Anything right or left is on me and delivery issues. But I also have to clarify that my experience is only with irons, I never got to the point of having any confidence or consistency with anything longer. I feel that is rather the point, as much as possible, to quantify the losses by trying to eliminate all the variables except the one you want to investigate. Or, I feel like we agree. Compared to the variables introduced by a golfer's delivery and the variables introduced by lie conditions, the losses from missing the optimal strike location might be so small as to almost be noise over a larger area than a pea.  In which case it seems that your objection is that the 0-3% area is being depicted as too large. Which I will address below. For statements that is absurd and true 100% sweet spot is tiny for all clubs. You will need to provide some objective data to back that up and also define what true 100% sweet spot is. If you mean the area where there are 0 losses, then yes. While true, I do not feel like a not practical or useful definition for what I would like to know. For strikes on irons away from the optimal location "in measurable and quantifiable results how many yards, or feet, does that translate into?"   In my opinion it ok to be dubious but I feel like we need people attempting this sort of data driven investigation. Even if they are wrong in some things at least they are moving the discussion forward. And he has been changing the maps and the way data is interpreted along the way. So, he admits to some of the ideas he started with as being wrong. It is not like we all have not been in that situation 😄 And in any case to proceed forward I feel will require supporting or refuting data. To which as I stated above, I do not have any experience in drivers so I cannot comment on that. But I would like to comment on irons as far as these heat maps. In a video by Elite Performance Golf Studios - The TRUTH About Forgiveness! Game Improvement vs Blade vs Players Distance SLOW SWING SPEED! and going back to ~12:50 will show the reference data for the Pro 241. I can use that to check AskGolfNut's heat map for the Pro 241: a 16mm heel, 5mm low produced a loss of efficiency from 1.3 down to 1.24 or ~4.6%. Looking at AskGolfNut's heatmap it predicts a loss of 3%. Is that good or bad? I do not know but given the possible variations I am going to say it is ok. That location is very close to where the head map goes to 4%, these are very small numbers, and rounding could be playing some part. But for sure I am going to say it is not absurd. Looking at one data point is absurd, but I am not going to spend time on more because IME people who are interested will do their own research and those not interested cannot be persuaded by any amount of data. However, the overall conclusion that I got from that video was that between the three clubs there is a difference in distance forgiveness, but it is not very much. Without some robot testing or something similar the human element in the testing makes it difficult to say is it 1 yard, or 2, or 3?
