To those who string Prince O3 Red sticks - do you guys always tie off the last cross at 9T which is on a cross and is marked on the frame as the correct tie off? I just restrung my O3 Red with a full poly, and found that the string traffic was just too heavy across 9T. So I tied off at 8T, which is a main. Interestingly, 8T has been enlarged by Prince as though they want you to use it as the tie off "grommet". Any comments?
