Somebody has offered me a paintjob with pt57a written in the throat. The grip size of these frames is 4 ¼ , unstrung mass is 350 grams, unstrung swingweight 344 kgxcm2, BALANCE IS 32.4 cm./324 mm./6pts.HL Is this the exact same racket as gilles simon is using or could it be a different pt57a? The seller said it was the same spec racket as gustavo kuerten uses, but i was wondering if it was also the same as the one gilles simon uses? I got to try one pt57a a while back ago, i remember it playing sort of dead, and it was heavy, but if you timed it right it was amazing. and it was very stable,and for some reason it made playing in the wind much easier. but i didn't find anything too great about it. What do those of you who have used it think about the racket?
