I briefly tried out the 2012 BLX blade 98 16x19 and they played not to differently from each other. The BLX was strung with NXT control and mine was full bed of Techinifbre X-One Biphase. I prefer more heavier racquets and the BLX was just a tad too light for me. My prestige was leaded up to 13.1 oz and the BLX was 11.something.
Racquet : TGK238.1 2X / Head YTPP 1X
