    5 Stars Outstanding Polyester

    I have tried all kinds of polyesters (luxilon, Wilson, babolat), but the Black Code is my favorite. I use 18g, so that in combination with the shape of the string makes for big time spin in a hybrid. Its also the softest polyester I've played with, so its great for preventing arm/wrist problems. And it seems to have adequate durability. I'm sure a 16g holds up longer, but I play 3+ times a week at a 5.0 level and might break 2-3 per year. Most of the time the crosses of the hybrid break first. Excellent string- a little pricey, but its worth it.
