I ordered two brand new Yonex RDS001 frames from TW and had them both matched. When the racquets arrived they had the following matching stickers: 11.9 11.9 12" 12" 288 288 The first two are the weight & the balance (strung), but the last one is a swingweight perhaps but doesn't it seem to be too low for the frame of that weight??? or was it measured before the frame was strung. In that case is there a way of knowing the current swingweight after it was strung without using the spec. machine? How does the 12" balance translate to HL balance???
