Driver swing weight reduction

[backintheswing]

My swing weight scale I bought off chappy turned up today, so I just measured all my clubs.

Ping i20 irons are all d2 and the pw is d4 - basically what I ordered.

Fairway woods and hybrids are all around D3 to D4.

My vokey sm4 wedges are d4 up to d6 for the 58.

This all seems great.

My R11 driver at 45" with a fujikura fuel 60s shaft with a 10 and 1 gram weight and a ndmc grip comes in at d8. I just made it up 2 weeks ago and have been hitting it very straight and longish.

Is anyone else playing d8 in a driver? I know if I want to reduce sw I can lower the weights in the head, but it actually feels ok. What do you all think?

[davidw88]

Wouldn't worry about it, If you hit it alright you might as well stick with it. You could also cut a bit off the shaft to lower it as well, or put in a counterweight if you wanted.

[razaar]

D8 doesn't ring true with that head, weights and shaft length.

[backintheswing]

The fuel 60s is actually 65g and it may be a smidge over 45", but it would only be 1/4 " if it is. I will pull it part over the weekend and weigh the head and measure it exactly.

[matty]

Probably feels good because you can't overpower it as easily as you would at a lower swing weight.

[Daves]

If it is working, leave it as is. Swing Weight is just an approximation for MOI fitting at the end of the day, and not always near the mark. Lots of things can distort it. MOI is all about matching your favourite club, not hitting some spec. If you want to play with it nevertheless, find a lightweight grip to suit.

[backintheswing]

Won't a light weight grip increase the swing weight?

Sorry correct, meant a heavy weight grip. I use GP DD2s on my Drivers, at 60g they drop a couple off a couple of SWs over the standard 48/50 grammers.

Yeah I have a couple of those here so will give one a try.

What ray said. 45 inches won't equal d8

[golf2013]

In the old days I played the callaway great big bertha at d8 but that was with a thin grip and a load of lead tape on the sole and on the toe.

[backintheswing]

Well I still have to measure the shaft and weigh the head, I changed the grip to a 59 gram and replaced the 10g weight with a 6 and its now at D4. The new decade multicompound whiteout was 49g, so I will see how this goes.

It's been known for swing weight machines to give varying readings between machines. I think the older machines work on a different calculation with the fulcrum point - 12" to 14".

Why question the machine when it's no more than 1 SW point over with all the other clubs?

The driver is simply longer than 45" or has a heavy head for whatever reason.

I think it may be a touch over 45 and I am yet to weigh the head.

What's an average weight for the r11 head without weights or tip?

[TheNuclearOne]

Not sure what they weigh as i've never chased one tbh. Big chance it's over 45" as opposed to heavy. For some reason i think they often come out around 203-204 in full cosi.

Ping SW specifications for the I20 irons are listed at D0 and D2 for the PW. Usually Ping are pretty accurate with their specs if every thing is standard. D8 struck me as odd for the modern driver with a 45" shaft. Machines can givevdifferent readings between machines. Tuna had two machines like this and ended up flicking one of them.

[backintheswing]

My ping i20's are 3/4 inch over and ordered at D2.

You missed the "basically what I ordered" for the i20's. His SW scale is close to spot on if not better.

[razaar]

Saw that but he didn't give details.

[mrbluu]

Any chance that there is a top weight in the shaft? I had a hybrid that played e0 when a matching hybrid played at d5. I took it apart and found a to weight. I drilled it or and it s back to normal.

However, I agree with the guys, if you are hitting it good don't worry about it.

[chappy1970]

The scale was always spot in for me before it found its way to Ash

My money is on this... 1/2 over = 3 SW points.

D4 or D5 with 45" is about what is std.

[davepuppies]

So if I had a matrix xcon 6, which weighs approx 67-69 grams, and took 1/2 inch off end would it feel lighter?

[TheNuclearOne]

Absolutely.

[backintheswing]

Shaft with grip and tip measures 44" and weighs 122g.

Head weighs 196g now with a 6g and 1g weight in it. So would have been 200g with the 10g in it.

Is swing weighting at d4 now.

Boom !!!

Nice one BITS.

[razaar]

Bits, I just did a calculation on your original swing weight with the details you have provided - head weight 207 gms (10+1), club length 45, shaft weight 60, grip weight 49, raw shaft length 44 = D8.
Your original reading was correct.

[TheNuclearOne]

It was never in doubt, tho it likely plays at 45.25".

The head weight with 10 + 1 is 200.

[razaar]

That would make it D4 by my calculations, using this calculator. http://www.golf-components.com/swing-weight-calculator.html

[backintheswing]

I find it hard to accurately measure the total length. I estimate it may be a touch over 45.25".

[razaar]

Measure it from the butt to the ground along the shaft with the sole flat on the ground for overall length.

You're not adding the 10 gram adaptor are you Ray ;)

Hey John, I was going to ask if you were related to the Crudd. These few posts remind me of conversing with Bob Katter.:)

One of us is talking Crud, that's for sure Ray.
