Just wanted to bring to any Nanospeed users' attention that the limited edition Nanospeed 9900 (Green) is approximately 1 point less stiff than the Nanospeed 9900 (Orange) on a 10 point scale if 10 is the stiffest. The feel of the racquet is NOT the same, they are very distinguishable. So before you go out and buy a Nanospeed 9900 (Green) be aware that it will have more flex which will make a change in your play. I have slightly less control with the Nanospeed Green. Thanks for reading, cheers.
