SONEX JP GOLD points the way to the future of rubber with built in speed glue effect that incorporates speed and spin plus good control. It has the qualities that will be essential when speed gluing is banned!
We recommend Joergen Persson's SONEX JP GOLD for ambitious attackers who want a well balanced rubber that has the effect of speed glue.
The donic sonex formula jp is a tensor rubber. It is harder than the soft version (see the other review). Basically, this is a speed and spin oriented rubber, but also with some pretty good control. The sponge is not terribly hard, i would say probably medium hardness. It is very elastic though, and the sponge is not very dense. Thus, you get a very explosive feel. you can really feel each shot dig into the rubber and spring back off, which i really like for looping. It is good for blocking too, though i seemed to overshoot a lot of my blocks. for counterlooping, it is pretty standard. I recommend this rubber to any offensive player.
