Everything I know I learned at the mould: the shape is decided in the first ten seconds, and after that you are only tidying up. That is co-polyester in one sentence, and it is why 660 feet of Head Sonic Pro sits on the shelf next to my moulds.
Sonic Pro is a firm co-poly monofilament, 16 gauge / 1.30 mm, sold here as a full 660-foot (200 m) reel — roughly sixteen racquets out of one spool, which is why clubs and stringers buy it this way rather than one set at a time. It behaves like good clay. It holds the shape you gave it.
You get bite on the ball, a low launch angle, and a string bed that does not balloon when you finally swing at eighty percent instead of a hundred and ten. Firm strings punish a lazy tension, so drop five to ten percent below your usual synthetic and let the ball sit in the bed a moment longer.
Bhubaneswar understands the material argument better than most cities. Start in the old town and look UP — the Lingaraja Temple runs its curved sandstone tower about fifty-five metres into the air, raised in the eleventh century by people with rope, stone and absolute conviction, and it organised the whole city around itself. One clear centre, one clear purpose.
Non-Hindu visitors view it from the platform outside, and that is fine too.
West of the city, the twin hills of Udayagiri and Khandagiri are honeycombed with cells cut for Jain monks over two thousand years ago, and I want you to notice how small the cells are: no windows, a stone pillow. And yet on the Elephant Cave here is the Hathigumpha inscription, in which King Kharavela lists his own achievements year by year in enormous detail.
Monks giving everything up on one hill and a king writing his own performance review on the same rock. South of Bhubaneswar, Dhauli Hill carries the Ashokan rock edicts, cut in the third century BC after the Kalinga war was fought right here and the emperor was so appalled by the slaughter that he had his remorse carved into the stone for everyone to read.
A conqueror publishing his own regret, permanently. And the small tenth-century Mukteshvara Temple, with its free-standing carved torana out front, is so finely cut that it became the model everything afterwards copied — you do not have to be the biggest thing in the city to set the standard for the city.
You will cut from this reel everywhere from a hard court in Bhubaneswar to a coastal court at Puri, an hour south, and by the way, it is also perfect for a morning at Dhauli afterwards, where somebody set a shape in stone and nobody has needed to tidy it up since.
