Recently when I visited Shuttle-House in Osaka to buy new badminton equipment, they were selling racquets from a brand called Air-Shuttle. It looks quite like a copy of an AT800 but I realised that it had so many extra grommets and when it's strung, it has 30 crosses.. Available in 4U2, 3U5 and 3U4. Price: 18000yen ( 150USD, approx 200SGD ). Interesting, but how do these extra crosses benifit the user/racquet ? Does it make the strings feel tighter/harder ? Increase string durability? And oh yeah.. their strings are 11.5m long to compensate for the extra crosses, whereas the others made by Yonex, Ashaway, etc are 10m long.
