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?
