Has anyone used the new ROK 100 (103?) and how it might compare with the Surge 100. Seem to be hitting more and more toward the upper limits of the sweet spot and might consider using something different. Have used the ROK 93 and like it but find I need something a little bigger. Presently used POG OS (107) and although I really like these racquets they are getting a wee bit heavy for me after a couple of hours.
