if you swing fast enough and make sure that you are going across the earth's magnetic field, you might be onto something.
yeah, i think that was the idea. just find an old racket and make it super heavy for training purposes.
wouldnt it rattle?.. i had put solder wire wound on one of my old racquets before.. it rattles after a while... 4 strips of yonex's tungsten tape will give abt 16-17 grams.. if stuck
But the racket itself looks nice. Never seen before. It must be a very old or a very new model? NS3000 or NS5000?
