well man here is my story ...
i got the blx ps 95 and it was the best racket i ever used performance wise ,i added 3 grams oflead at 12 o'clock andit played so well , great cominationof power and control , easy to manuever, improved my 1 hbh massively that it wasnt a weakness anymore but a weapon , very smooth on volleys and very quick at the net. all was a dream for me until i picked up a wrist injury that i leaving me out of tennis for 6 months, and i believe its because of the racket as i heard so many people complained from this particular stick that it caused them wrist and shoulder injuries.
in my last recoevring days i decieded to get the PS 85, ( well i was bored without tennis and i am a huge sampras fan and had to own one ). i thought i cant play with it because of its weight and small head size but it is so head light that u will move it around better than any other stick, if you are a 4.5 player or above it won't take you much time to get used to it.
i stringed mine with natural gut babolat at 55, feels great but i will have to add some weight on the top because it is very low powered.
still i have this feeling inside me that i cant play a tournament match with it. i will wait till iam fully recovered and practice more with it.
