A friend of mine runs a tennis shop and suggested we'd check a few of my racquets on his RDC-machine. FYI, they were all strung (weight) but had very old stringjobs in them (flex, for what it's worth). I have not converted the weight from metrics, but there are conversion tables readily available online... Sorry, no balance numbers this time. Here are the specs: (Weight Flex Swingweight) Adidas GT-X (Lendl) 340 g 53 314 Prince woodie 376 35 335 Prince Mono (Connors) 349 62 326 Le Coq Sp. TF-40 (Noah) 356 60 342 Lacoste LT301(?) (Forget) 358 62 330 Estusa PB Braided 356 63 311 Rossignol F200 349 33 345 Rossignol F250 358 60 349 Sergio Tacchini Syncrony 383 56 355 Prince Boron LB 338 58 338 Yonex RD70 long (Kourn.) 348 58 347 Spalding pro stock 200 365 69 345 Some numbers really stood out, like the flex of the Rossignol F200. 33 is soft... The Boron was also way softer than I thought it would be, at 58. The Tacchini is a monster, but I'm having that one, and the F250, restrung to play with again later. I'll probably bring some other racquets in to check on the machine, in which case I'll post the results here if you're interested.
