How many degrees does boosting a rubber soften the sponge by

[Dman]

Curious to know this. I’m thinking of getting a Yasaka Rakza z or z hard and I’m going to boost it but I want to know how much it softens the sponge by so I can decide. ideally I would like it around 48 to 50 degrees.

The newer esn sponge right now seem not to soften much with boosting unless it is not less than 3 to 4 layers of boosting and that depends also on the booster being used.

I will be using Falco tempo long booster

It will only soften a lil bit using falco but curling will be hard to flatten.
