Once I got to the courts 4S was about what I expected from a geometric poly—spin potential was above average and feel was solid though not as crisp as I typically like. The flipside is that 4S felt very soft and was one of the most comfortable polys I've used in quite a while. Fortunately the soft feel didn't come at the expense of durability. I played past the 12-hour mark with my set and didn't break it though they definitely felt a little dead towards the end. As I've noted in the past I find that most polyester strings go dead and lose tension well before they snap though I'd expect that heavy string breakers may break Black Code 4S before it goes dead or gets mushy.
