This is a very good rubber although it's ratings are a bit misleading from my experience. I would say that this rubber has many gears due to it's thinner top-sheet. So it is fast but it takes a little more to get in that "pop" from the sponge. Because of this it has great control for the speed and spin that you can deliver. I would rate this: Speed-94 Spin-91 and Control-76. This is not a good rubber to replace tenergy rubbers! Although you may come to find that you like it anyway. The true determination that tilted the scale for me to give this 4 stars instead of 5 is the price 5 to 10 dollars less and it would be definitely something for other companies to compete with.
