I'm using Luxilon strings for my tennis rackets. Same strings Agassi using Not sure if they got badminton strings
did a quick search, they did have string for badminton.. i wonder what its performance compared to common strings (yonex, gosen, ashaway..et.al)
i've heard of it from a friend selling sporting goods. according to him it is a natural gut. made in belgium. can withstand high tension stringing. but comes in natural color only.
