Just curious on how heavy you tried a racket at. I'm currently playing with my 13.5oz k90 with a swingweight of 355. I used to play for a high school team, and many people tried to use my racket. They complained that it's really heavy. They even asked me how did i get used to it. almost all of them use a pure drive plus because of coach. I like my racket because it stands out from the rest. it also unique to my playing style and almost everyone can't use it.
