New sanwei rubber. It is a tuned target national.

Yes, FP is falco platinum. The massage gun is the cheapest one with cushioning ball attachment. I use a sheet of 729 super to cover the surface of the new rubber. I put the stack between 2 sheets of cooking paper and pressed with the massage gun most of the surface, from the sponge side. Sometimes I measure 1-2 degrees softening of the sponge, but most of the change is in the reducing of sponge damping, or energy loss during rebound.

Have you measured the hysteresis or is this just some impression? I can't really say I've ever used *any* rubber that didn't just become slower and less bouncy after use.

I am using durometer on multiple points, from the sponge side. Bounsing test is subjective. After treatment the rubber is more consistent across the surface. My impressions are mostly on slow, middle to hard rubbers.

You should just measure the bounce height when dropped at low speed. The CR is highest at low speed, around 0.5 to 0.7, and the deltas will be the highest if there is any. I've only ever found lower CR which is consistent with breakdown of the sponge.

Cuifeng more heavy and hard and Chinese blue sponge like. Durability is very good. It's not that bouncy but not slow it's hard and quite fast. Needs good power to be hit through but if you manage to it's so good and rewarding.

what do you think of pinyi cuifeng blue sponge 37-38 degree version?

I always preferred h3 bs 39 because its easier to hit through, there was even a time where I used boosted h3 37 os on fh and liked it

wondering which version (37-38 or 39-40) fits me better since u said pinyi cuifeng is quite hard
