Does anyone here have experience with both rackets? Is there any specs on the RD-7? How it compare to the RDX 500? I have been using RD-7 for the past 10 years. I currently have two right now but I crack one of them a few days ago. I am looking at the RDX 500 as replacement. Picked up a demo today and feel a little bit different. Though is better than the recent Yonex that I have tried in recent years such as the ti-50 and muscle power series. Any ways to modify RDX 500 so it will play more like the RD-7? Other Yonex alternatives? Thanks in advance. Need all the feedback to help me decide!!
