I'm thinking of adding some lead tape to the Yonex RDX-500 Midplus demo I currently have in hopes of making it as stable as the RDX-500 Mid (or as close as possible). My question is: if I add some lead tape (say a total of 4 grams - 2g at 3 o'clock and 2g at 9 o'clock) to the Midplus, how much will that effect the balance point of the racquet? I know it will make it less head light, but is there a way I can tell how much (points) less head light? Also, is there any way to tell how much the swing weight will go up (I think it is 315 off the shelf)? Thanks. TripleB FYI: I am going to get an RDX-500 racquet, just trying to decide which one. Like the put away power and volleys of the Midplus...like the serves and returns of the Mid.
