String weight and swing weight

[teocem]

I think racquet swing weights should be stated as an "unstrung" spec only.
String weights change a lot according to string type, racquet head size and string pattern.
Considering a 100 inch racquet a heavy poly may weigh 19 grams and a multi fiber may add 12 grams. The difference x2 is 14 and this is a significant difference in swing weight.
So if you buy a racquet from TW you may see that on their website the swing weight is 320 while your racquet measures 309 and you get frustrated by this big difference.
Therefore I advise them to use unstrung swing weight instead.

But no one actually plays with an unstrung racquet.

The point is to know the swing weight spec of the racquet in your hand, if it is off spec or not...
It is the same with weight, we add also over grip, vibration dampener.
Good to know what you buy.

I would add that demos should come with actual specs as well.

I wish I could dislike comments..

I have a Prince phantom that has the unstrung swingweight listed on the throat. Don’t recall any other racquet having the SW listed

 

[teocem]

Is there any website that gives unstrung swing weights?

It's a good idea, or at least companies should state the weight of the strings they used when quoting the strung swing-weight. I know just 3-4g in the hoop can make a noticeable difference.

As you probably know, just subtract 30 from the strung swingweight, because it's always measured with 1.25 poly as standard anyway, at least on TW. If youtubers speak of swingweight, then also pay attention what string profile they have in the racquet

For most players strung swingweight of 325-328 will feel best for a 305g frame, perhaps 320-325 for a 300g frame

So that means that you're aiming for 290-295 unstrung, and then perhaps just add 1-3g to match racquets to your preference

If you buy a racquet with unstrung sw of 298 for example, that will often be an issue if you want to match more racquets later, or if you need a bit of lead on the sides etc, so it's just better to have it sligtly lower. That's how most pro racquets are also made, with very light specs

Swingweight is rarely, if ever, a spec provided by manufacturers. So whether or not you know what it is, strung or unstrung, what are you going to compare it to to know whether any particular racquet is “on spec.”

This is a rhetorical question because you ignored this exact same logic in the FX 500 thread.

You want swingweight to be a standard metric by which manufacturers measure quality control but it isn’t going to happen. Move on.

Racketpedia, fantastic for strings tests too

There is definitely more interest from consumers in the swingweight and twistweights of racquets. We can only hope that this does actually lead to manufacturers both listing and tightening their QC on these previously invisible specs

As nowadays we pay 250 USD for a racquet we have the right to ask for better quality control.

 

[teocem]

Can two unstrung racquets of same model and exactly same weight have different unstrung swing weights?
I presume yes because the distribution of the weight in the frame may be different even though the balance point may be the same.
And this is being overlooked..!

Average value by testing a bunch of same model unstrung racquets.

Yes. It's usually the case that swingweights differ, often by a lot. Yonex is easily the best, and Wilson is usually the worst.

It's not being overlooked, this forum is full of those stories, for 20+ years already. And of course the manufacturers know. They just prefer the cheapest way to making carbon frames, instead of best, or optimal. 99% of buyers don't know, and usually don't care even if they know

Racquets can easily be customized but I am sensitized against adding weight to the frame; I feel it takes away the liveliness of feedback that I receive when I hit the ball.
I can even feel that with as low as 2 grams anywhere on the hoop, it is like a curse.

Feedback is useless because tge ball is already gone by the time it registers

All specs should be unstrung only.

Stringing depends on multiple factors such as the weight and tension of the strings.
Strung specs are a total abomination.

That’s not how economic inflation works.
