My gf just got this racket and I string hers with full OGSM 17 @ 64. She loves it.
It's a bit higher than the recommended range, but I just started doing my own stringing and saw a thread about how OGSM looses about 8lbs of tension quickly and then settles. After testing it, it's spot on- so it ends up being 56lbs after an hour or two of hitting.
