I was intended to by Yonex Voltaic i-Force or Voltaic 80. And got to know about CARLTON KINESIS X900 LIMITED. I do not know much about Carlton. Please help me to sort out.
There is quite a lot of information about the x900 in this thread http://www.badmintoncentral.com/forums/showthread.php/123457-Carlton-Kinesis-X90-X80-X70/page6
