Normally soft is a slower version of the harder sponges for the same type of rubber but not so with C-1. In fact, this is the fastest for its type on the market. This rubber has more grip than S-1, but the control I think is the same. Looping is fabulous with this rubber along with chopping and blocking. I like it for serving too and it also handles the new plastic balls well. So if you are an advance player looking for a quality rubber to play with, consider this one!
