Finally strung my set of Prince NG 16 up, the one in the green packaging. Strung in a Wilson k6.1 95 16 by 18. I've now put around 5 hours on the string, and it's barely moved! These five hours have been against the guy I usually play, and we both hit pretty hard. Usually, multis and synthetic guts move all over the place after an hour or two of hitting. My previous gut setups (Wilson NG 16 mains with E-force 18 crosses and Global 16 mains with blue start 16 crosses) moved all over the place as well. I'm not sure if it's because I've strung NG in a full bed, but this stuff just doesn't really move!
