    Can anybody make a list of players using mid frames and their swingweights? Federer is obviously first on the list with 338

    Murray went from 400 to around 370, not 340. 345g is his static weight, he dropped it from around 355g. Greg Raven's specs are not outdated, it's the K6.1 paintjob, it's from 2009 I think.

    But it's not clear if Greg got this racquet with or without lead under bumperguard, where Roger currently use it ( according P1 pictures)

    It's after, because he has the little sticker with Roger's name and tension right above the grip tape. I believe they only add the lead tape for matching purposes on his K6.1.


    What about hewitt's SW, any info on that?

    I would also think 362,5 g's is with overgrip and a bit of lead to match the frames.

    24 inches? 24 inches would be 24 grams under the bumper, meaning his SW would be 336 + 24x3=408 kgxcm2. We can easily find out how much lead they put at 12 for his K6.1 by taking the racquet's static weight 354g, add an overgrip and powerpads and it goes to 360g. We know that he has to get to a static of 362.5, meaning he adds 2.5g at 12, which wouldn't raise the SW by more that 6 points really.

    He might also start out with the lighter of the K90s that wilson makes.
    There's really no definitive way to know without getting his racquet.

    And I guess 24 was really far off, maybe more like 12. (still an estimate. I'll try to find the pics. )

    Here is picture of his real K Factor racquet on the scale and it was 365g ( it was posted here). So maybe 5grams at 12 then?

    Also somebody was counted how long was his lead on P1 pictures and it was like 3-4 grams .

    3 grams at 12 is like +9 on the swingweight. You'd expect the specs on each stick to vary a little though

    Anyway, could we please drop the federer SW debate. a professional racquet technician has his frame as played and until we get someone else to put fed's stick on an RDC and tell us the readings, those are fed's specs.


    Anybody know about hewitt?

    I'm not quite sure yet. As far as I know, Wilson has not made any claims that Federer has actually switched, like they did last time. If I were Federer, I would not switch to such a dead racket. But maybe he really did. Then again, the note on P1's new pics said "new pj", or something along those lines. Though they wouldn't know the difference as they don't hit with them and they probably wouldn't notice a difference anyway.

    As for the high swingweight, it wasn't holding him back so much as it was too much for him to handle. Yes, injuries do hold you back, but the racket itself wasn't the direct cause of him being held back, more like it promoted the injuries that did that. That's why I advocate not going for more than you can handle.

    That's a very bad estimate... It looked closer to 6-10 inches based on the racket, which means 3-5 grams (since it was 2 strips; one on each side of the strings).

    The lead they use is .25 grams per inch. That means it's +6 grams. Also, I don't think your calculations are correct, but I'm too lazy to check. Probably closer to a 10 unit increase.

    Shouldn't be that high. Greg Raven got a hold of Federer's finished custom K90s and the swingweights weren't that high. Federer isn't the type to make drastic changes.

    You can easily take that specs from they company that actually customizes those rackets comenting on the leading etc and gave actually picturesLOL

    Greg's specs are F'ed up. Gasquet's SW is not ~384, and is impossible with the static weight and balance.

    Also wanted to add, other people the own the actual racket of these different players have measured different specs than what Greg has. IE that very Gasquet racket, which said person actully recieved on court from Gasquet himself.

    I think they would notice, since I noticed from comparing the two rackets (they are a different mould). Also I think they would know, being the top racket technicians/experts, working for the top player of the era.

    As disappointingly confusing as this is for those who want to know the exact specs for the rackets of professional ATP players, their specs actually do vary from tournament to tournament. Sometimes it's as little as 2 grams. Sometimes it goes up to 7, or even more, for the differential.

    Really now...? I'm pretty sure they're of the exact same mold. If you could post your findings and if possible put up pictures as well to support your findings (as I don't own a BLX90, but am thinking of buying a few since I can get it for $110, though they do suck), I might agree.

    Also, we've asked them. They DON'T know other than the insider information they've been given. I'm pretty sure they don't go to Wilson's factory to pick up Federer's rackets, the rackets are shipped to them. We've also received confirmation from Ron Yu that they don't hit with his rackets, and that even if they did they wouldn't notice any difference.

    They may be great racket technicians, but they still are only experts in matching, customizing, and stringing rackets. They aren't experts in EVERYTHING that's racket related.

    I have compared the two in the shop (K 90, BLX 90). The dent in the racket for the bumperstrip is differently shaped, hence different mould.
    And I just dont agree with you on your other point, but ofcourse you are entitled to your opinion and beliefs.

    I currently own the youtek radical pro, which is the same racquet used by Andy Murray, and the swingweight is 345. The racquet is somewhat like @ 11.1 unstrung, but because of balance point, it swings like its a lot heavier. Personally, i love it.

    Gasquet's specs look quite realistic to me. He does use a larger headsize which demands a higher swingweight for stability. Keep in mind his racquets are over 27 in. so a very high swingweight is easily achieved.

    I was joking man. But in general I use the USTA calculator, punch in the specs of a racquet and then use the tool to add weight at different locations. This provides me with a really good estimate of what I'll get after adding lead, and I've noticed that adding lead at 12 o'clock (67-68cm point) adds 3 SW points per gram, whereas adding lead at 9 o'clock (54cm) adds roughly 1.9 SW points per gram. It's quite useful cause if you only have 1 or 2 racquets you can know their measurements by heart and estimate your swingweight before you try a different setup
