I have three BLX Blade 98 rackets. One of them is newer and I ususally do not like to play with it. It just seems heavier. I weighed all of them this morning on a postal scale and got the following results. The rackets should be 10.7 ounces unstrung. I did have an over wrap on the grip on each racket. Also, each one had string. Racket #1 11.4oz strung with full bed of lux Racket #2 11.4oz strung with full bed of lux Racket #3 11.7oz strung with a hybrid of lux and NXT Is that a significant difference? To me the racket does not even play like the other two.
