i’ve tried it. felt like i was going back to the 90s with speed glue and 38mm ball.
the rubber is hard and bouncy - great for smashing. old players would love it as it helps with shorter and weaker strokes.
Yes good point, it is very catapulty rubber almost like speed glue. Very intriguing rubber but it would probably be better in a 47 sponge. I think its a little hard to use due to the hardness and also the low throw angle.
