Also known as “synthetic gut”. I think this is the most misleading description of a string, ever. It is NOTHING like gut. It’s stiff and doesn’t give. It’s basically nylon. Most synthetic strings actually are made of nylon. But it’s much sexier to call it “synthetic gut” than “nylon”.

Having said that, nothing is wrong with nylon and not all nylons are made the same. This one in particular is as stiff as polyester but has a lot of stretch to it which is good for you arm. It’s low powered, very much like a poly which is good for controlling powerful racquets. And it hybrids extremely well with other strings I’ve chosen.
