Anyone try out the reg Roddick and the Roddick +? If so which one did you like better and why? I really cant choose which one to pick, I'm slightly leaning towards the regular Roddick, but really want that extra power from the Roddick +. Also, for those who have the Roddick +, does the extra half inch in length of the racket cause it to be "sluggish" in any way? Thanks a lot guys!
