Got a half-set of the 17g from my stringer nearly a month ago. Strung it at (high 50s?) lbs in the mains of my RQIS 1 Tour (red/black) with Prince Lightning 16 in the crosses. Didn't like it too much at first. Honestly, I'm not used to anything but 16g strings. But they are growing on me. Nothing amazing, but the spin is there. And they look cool, if that matters.
