after all this years, borrowing this topic.
I came back to ProStaff RG97A, and the time for new string is coming up. currently Signum Pro Hyperion string is in the frame, but I feel it's lacking a bit in the spin department ... one thing is sure, I will drop tension from 25/24kg for a kg (to 24/23kg). in my other Wilson frame (older Wilson Ceramic FP) I have Signum Pro Tornado (at 25/24) and it plays great. is ProStaff sensitive to string choice?
