I just find it ironic that these two have similar paint jobs. I plan to upgrade my from a Muscle Power 7 in the near future. I prefer head-heavy and mid-flexible racquets and enjoy both faking smashes and smashing, but I can do close-up drops if I have to. What are your own experiences with the two? Specs if possible, please.
Arc7 should be slightly flexier than the SW31. The Arc7 is more all round than the SW31 in my opinion.
