Spring Sponge vs Spring Sponge X vs ESN Sponge

[ZFT]

This is based on subjective feelings so any comments or opinions welcome 😃

In relation to grippy type rubbers with which I have more experience.

For me Butterfly’s Spring Sponge has a feeling of vibration/reverberation spreading across the whole bat face from the ball impact point (like tsunami waves spreading outward from the epicentre) whereas ESN Sponge catapults out directly from the impact point within a tighter circle (like a volcano).

Spring Sponge X is in between.

The thicker the ESN Sponge the more localised the catapult - i.e. Max+ variants.

Is this in line with what you have experienced or felt?

That's deep and poetic!

yeah, like yet another attempt to describe to us the taste of chocolate 🤣

Does chocolate rubber taste good?

But seriously does anyone find this difference?

Yes, there is a difference. In fact, that is what Sumitomo focused on in the development of the Q series.

The only difference between the three sponge materials is in trade name. They all have borrowed an advanced rubber formulation as first developed by an American chemist engineer back in 1965. It is scientifically called "syntetical polybutadiene rubber", featuring hellish bounciness on impact.

You're sure it's not "flubber" ?

So why can only German and Japanese companies use this formulation?

My question is whether the comparison is correct if made so generally.
Spring Sponge to my understanding is one sponge available in different hardnesses - tenergy rubbers differ in topsheet design, not sponge.
ESN has many different sponges, so I don´t think you would have the same experience with large vs small pores or high-end rubber vs entry tensor, etc.
Or do you think the characteristics apply no matter what? I am not so sure...
