17 g is really 17, which you can see on the sticker. Don't know why people are complaining about that. I've been hitting with these strings for a year. They're a stiff monofilament poly, but that's what I look for. I'm able to pick up heavy balls and generate spin off them still. I hybrid it with synthetic gut in the crosses to keep some comfort and control. I string it at 50lbs, and you probably shouldn't do much more than that if it's poly anyways. I'll keep buying them until it's discontinued. Awesome deal. 4.5 USTA player.
