I'm terrible at describing this kind of thing, but I wouldn't say that it's crisp. I would call it smooth-feeling and responsive - it's got silicone oil infused in it, and remains quite slippery. It's a smooth/round string, and so would definitely be a great cross for any hybrid. But, it's very comfortable as well, at least at round 43lbs - it almost feels like playing with a full bed of syngut, but it acts like a poly (snapback and spin/control).G tour sounds cool. What does it compare to and is the feel crisp?
I think the pk has a leather grip and the listed spec I saw is 19mm.
At contact, I feel like it has less bite than the Cyclone I'm used to, or any another shaped string, but I think the spin levels are almost the same based on what I see coming off the racquet. I also like it because it seems to have a bit of extra pop on the rally ball, but if you lean into it, it's not out of control.
