What is softest sponge of Loki rubber.

[TT Lover]

Good day to all TTD members.

Please kindly recommend the softest sponge of Loki rubber.

Thank you sir.
Best regards,

Loki Telson 100 comes in mid-soft sponge that is advertised as 45 degree Shore O.

It is not only about the sponge hardness, the top rubber itself can also be soft. I am having a great time with rxton 3 pro, it plays same as Butterfly Rozena

Softest Loki rubber I tried was T3 Speed it said 35° felt really soft, only usable on BH, probably best with a hard blade.

LOKI did a lot to confuse customers, they seem to use different hardness scales on different rubbers.

We just advised ITTF to update M4 technical Manual as follows:

📌 2.7 PACKAGING

DESIGNATION OF RUBBER PROPERTIES.

-- A hardness value shall be indicated either by Shore А or by Shore O scale or both. The type of hardness scale must be еncoded with letters HA and HO respectively.
-- Hardness scale of a different type shall not be used.

EXAMPLE.
HA 42.0°
HO 52.0°
HA 38.5°
HO 48.5°

-------------------
Be happy all

Yes they use the same scale as DHS for the most part but for some rubbers such as the new telson they seem to use Esn scale...😵‍💫🤷

I do not think that ITTF will be bothered to get involved in this.
Remember : " Whenever you make a rule - somebody will have to be able to police it."

Maybe the manufacturers should instead just stop bullshitting us with giving us numbers that are pure fantasy anyway and call the hardness of their rubbers more like:
SOFTISH
HARDISH
SOMEWHERE INBETWEENISH 😁

Yep. T3 Speed is the softest...

I watched the Russian review of this rubber. He had 475 version. He said it's in Japanese scale because it's even harder than D09c.

I'm inclined to believe the reviewer that it was harder than 47.5d.

But it's probably more likely that Loki was aiming for a softish sponge of 47.5 ESN and missed, rather than using the Japanese scale and trying to market a 57.5d ESN sponge as a medium hard backhand rubber.

You sure about that? I always thought that 41 is about 57,5... The Jekyll C55 felt much softer than DHS H3 40...

 

[loki-sport-uk]

Hardness is measure by hardness of the sponge the overall felling is going to be always different as it depends on rubber elasticily and pimples structure so what you are descributing is true. Some rubber which seems to be harder migth fell soft.

I've seen quite a lot of variation in Loki rubbers when I've fitted them for people at my club.
I fitted an Arthur China and Arthur Europe Diamond a few days ago, the China (listed as extra hard) measured 54 degrees Shore O, and the Europe Diamond (listed as medium hard) at 55.
The old Kirin K5 I removed had a 4 degree difference between the red and the black

I think the chart is only a rough guide. They show the euro hardness as always being 10 degrees higher than the Chinese, when it isn't as linear as that.
There is a thread here: https://www.tabletennisdaily.com/forum/topics/a-bunch-of-questions.15840/
and chart https://www.tabletennisdaily.com/forum/attachments/img_0621-jpg.12546/ which seems more accurate

That lines more. When I measured the C55 it was 38-39 Shore A

Many thanks. We have updated the tool to what the community is using.

There's no actual conversion that you can just use for TT sponges. Charts like that are industry guidelines for measuring uniform, thick and relatively non-linear objects, so not TT sponges. The topsheet interacting with the sponge also complicates it a lot and real-world measurements will differ quite a lot from theory and manufacturer reports unless they did just report the actual unit's hardness.
