I recently started playing with a blade 18x20 after using a RF97 black. I love the weight, plow and stiffness of the pro staff but decided to give the blade series a try. The v7 was great for serving, but had too much flex on ground strokes. I added some lead tape to the v6 18x20 and started beating players I would always lose to. So decided to make the switch to blade. I would like a little more spin, so thought about the 98s. I can not find any 16x19 in my grip size. Has anyone used those racquets? How did it perform?
