Have recently posted a thread on the stringing forum after I had problems stringing my Ki5. Have since found out it has an 18x20 stringing pattern but should be 16x20 as it says on the specs. Was suggested it was not genuine but having looked at pics mine is exactly the same (apart from the extra grommets). Bought it resale although it came to me new and unstrung and, having read an old thread on Pro Kennex rackets wondered if it was a Seppi racket? Any thoughts anyone, would be interested to hear??
