I'm trying to find a racket suitable for doubles all-around play. How would either racket fare in the front/back court for a hard hitter? I am also wondering how tk9000 feels upon impact. I'm hoping to get a racket with minimum shock-absorption, and something with as solid feel as possible. I know tk9900 has one of the most solid feels, but would tk9000 be considered a 'numb' racket?
