Why do inner fibre blades basically just use 2 compositions?

[TensorBackhand]

Pretty much every inner-fibre blade I have seen only uses 2 compositions:

1) limba-ayous-carbon-ayous core
2) Koto-ayous-carbon-ayous core

Why are these 2 so standard? Are other potential wood types bad for inner blades? Spruce, Hinoki, etc? Nothing else would be a good blade?

The Donic WC89 series all uses spruce for top layer. Waldner is an inner…

So how would that change the function vs limba and koto?

Koto and limba are the 2 most widely used wood types because they're pretty balanced in terms of characteristics. Other woods are not as popular for inner composition because they are not as popular bottom line

This is interesting I've only seen a couple differences like Sanwei Paramid ayous-spruce-aramid-ayous, and Stiga's Inspira CCF koto-limba (or ayous?)-carbon-kiri, I thought 75 Inner was the same, but it has an ayous core. Is there any other inner fiber that has a similar composition as an Acoustic Inner limba-limba-carbon-kiri, but with alc or klc?

The Sanwei Paramid and F3 Pro seem softer than other blades, is that because Ayous-Spruce is softer than Limba-Ayous?

How does Inspira CCF play compared to other blades?

What would using Hinoki do to a inner fibre blade?

I'm just looking here, it seems like Limba and Koto are already the hardest woods among the commonly used woods. So anything maybe Hinoki or Spruce or others would only make the blade softer.

The same way as on allwood blades. I don’t know what it is but with a hard layer under the feel is great. Appelgren WC89 is an outer with some kind of zylon underneath. I can’t get enough of the feel. The Waldner WC89 is (I think) an inner blade with a thicker core. Also has a good feel but I prefer the Appelgren.

I forgot about the classic Joola Rossi with hinoki-koto-carbon-ayous & Aruna that replaces the ayous with kiri.

From everything I’ve read & watched the Inspira CCF is extremely fast. Even faster than Viscaria and some outer blades.

I think that makes sense that CCF would be faster, because Koto-limba is harder than Limba-Ayous

Some websites state that Sanwei 75 uses candlenut wood core rather than ayous. Seems possible. It feels slightly less stiff on contact than my other inner carbons.

Candlenut wood is in between kiri (softer) and ayous (harder) in terms of hardness.

JOOLA classic carbon also used candlenut wood core.

Nittaku acoustic Inner carbon has a tong core (paulownia same as kiri). It plays more springy and hollow than the ayous core blades.

The constraints of weight and stiffness. You have to strike a balance between those two, and on top of that you have to consider the feel. Plies of different density and thickness are combined to accomplish that but the range of manipulation is rather narrow, and the closer to the core the less effect on the natural frequency (other variables kept constant).

That's why Stiga had been messing with the top ply for the most part in the last 15 years. The Cybershape is essentially a clone of Viscaria that had been on the market for 28 years.

Butterfly ALC.S has spruce

There are plenty of inner fiber blades on the market that use different woods, you're just not looking hard enough.

But, as already mentioned, Koto and Limba are the most popular, for several reasons.

Not the same: Cybershape is inner carbon while Viscaria is outer carbon

That's why I used "essentially" and not "exactly". As I wrote in my previous post, "the closer to the core the less effect", and the two blades are grouped relatively close by TTGearLab, closer than other Innerfiber blades by Butterfly, which have different compositions.

2-1. Elasticity Indices
...‘Cybershape Carbon’ can be categorized into the group that includes ‘Shang Kun Hybrid ZC’ and ‘Carbonado 190’ those are quite fast, but not extremely fast blades. ‘Shang Kun Hybrid ZC’ and ‘Carbonado 190’ are placed very close to ‘Cybershape Carbon’. (‘Viscaria’ can be also categorized into the same group, although if is a bit less close to ‘Cybershape Carbon’.)

2-2. Vibration Indices
...Especially ‘Cybershape Carbon’ is harder than all other blades in this comparison. (But, some players will still feel that ‘Viscaria’ is harder than ‘Cybershape Carbon’. That is because the artificial fiber can be felt more directly from the ‘outer-fiber construction of ‘Viscaria’.)
