This is Spectol with the very fast red sponge behind it. Not as controlled as most of the tension-sponge pips out there because it isn't as spinney, but soooo fast with a flatter shot trajectory due to that lack of spin.
This is a hitting/countering rubber and as long as you hit on-or-before the top of the bounce, it's tremendous.
Blocking is good but a little fast, so likely better with S1 or S2.
Pushing has to be early.
This is not a rubber to chop with.
