This is the entry level to the Japanese-made Nanospeed series. Surprisingly, I find this racquet heavier than the new higher-end Nanospeed series like the NS3000, 5500, 6600. Similar to the other mid-end racquets like the NS3000 and ARC3FL, it comes in two colours. I wonder what is the rationale behind this as both of them are the same in specs. I think it is another way of getting people to buy more racquets .
