I have used all of the new BK rackets, Photon, Feather and Ghost. Despite their benefit of being light, they do pale in comparison to that ok the quality of Yonex rackets in my opinion. For similar reasons to that of a Japanese famous Table Tennis company called Butterfly, their products do not need advertising because they sell themselves. Also, they rarely upgrade their models since people are so comfortable with the technology that is out already. It will be interesting to see what any company can come out with next because if you ask me, they have reached their limits. This applies to all four racket sports in my opinion, take it from a racketlon player. Also, equipment does not make up for technique.
