Gwalior Fort
Diadem Evolution 15L Tennis String Reel: Provenance first. Founding: attributed to the chieftain Suraj Sen, sixth century – attributed, note that, tradition rather than document. Custody thereafter runs Rajput, Delhi Sultanate, Mughal, Maratha, and I would want each of those transfers signed. A hundred metres of sandstone, three kilometres of wall. The Man Mandir Palace is Man Singh's, Tomar, 1486 to 1516, tiled in blue, yellow and green with ducks and crocodiles on the outer walls. Babur is said to have called it the pearl among the fortresses of Hind – said to have. And a ninth-century temple inscription up here carries one of the oldest written zeros known. A zero. Filed in stone.

Jai Vilas Palace
Diadem Evolution 15L Tennis String Reel: 1874. Maharaja Jayajirao Scindia of the Gwalior princely state; architect Sir Michael Filose; Tuscan, Italian-Doric and Corinthian, entered under three headings because it refuses to sit under one. The Durbar Hall carries two of the largest chandeliers in the world, three and a half tons apiece, and the account that elephants were hoisted onto the roof to prove the ceiling would bear them is repeated everywhere and sourced nowhere, so I record it as tradition. The silver toy train that ran brandy and cigars round the dining table on rails: catalogue it under transport, or under tableware? I have never settled that. Family still in residence; the museum wing holds the artifacts, weaponry and carriages.

Tomb of Tansen
Diadem Evolution 15L Tennis String Reel: Cross-reference – this entry cannot be read without the one beside it. The modest tomb is Tansen's; the far larger sandstone mausoleum next to it is Muhammad Ghaus, the Sufi saint who was his spiritual teacher. Tansen, born near Gwalior in the sixteenth century, the most celebrated singer of Hindustani classical music, one of the navaratnas, the nine jewels of Akbar's court – and buried plainly, because this is a disciple's file, shelved beside the master's. The tamarind tree is fabled to sweeten the voice of anyone who chews its leaves; folklore, and catalogued as folklore. The annual Tansen Sangeet Samaroh, the national classical music festival, is held here.

Sas Bahu Temples
Diadem Evolution 15L Tennis String Reel: Here is a cataloguing error that outlived everyone involved, and I am quietly delighted by it. The inscription gives the name as Sahastrabahu – Vishnu, the thousand-armed – dates the larger temple to 1093, reign of the Kachchhapaghata king Mahipala. Over centuries the tongue wore Sahastrabahu down to Sas Bahu, mother-in-law and daughter-in-law, and legend then obligingly supplied two women of a royal household to have built them. A corrupted title, then a story invented to justify the title. The larger runs three storeys, pillars, brackets and ceiling panels carved solid; the smaller is one open pavilion, damaged, and every bit as fine.
Gwalior's fort runs three kilometres along a sandstone ridge a hundred metres above the city, and Babur called it the pearl among the fortresses of India. Longevity is the local speciality, and it is this string's too.
Diadem Evolution is a polyamide monofilament finished with a low-friction silicone-based coating — not a polyester, not a multifilament, but one solid nylon-family filament with a slippery skin that lets it slide through the crosses instead of grinding itself away at every intersection.
This is the 15L at 1.35 mm, the thickest gauge Evolution comes in — the range is 17 (1.25 mm), 16 (1.30 mm) and 15L (1.35 mm) — and it is here for one reason: it lasts. On a reel it lasts twice: 660 feet, 200 metres, roughly seventeen to nineteen racquets, which is the format for a player or a coach who restrings on a calendar rather than after a catastrophe.
Colours are Natural, Black, Azure Blue and Pink.
Diadem's own case is precision, comfort and easy power, and the design brief was explicit: handle the sharp edges of hard shaped polyesters. That is why it is such a durable hybrid partner, and the Tennis Industry Association has rated it a top string.
The honest sell is this — at 1.35 mm, in a coated nylon monofilament, you get an arm-friendly bed that keeps playing long after a co-poly would have gone dead, which matters most to the player who has been at it for thirty years and intends to be at it for thirty more.
You will use it everywhere from a hard court in the shadow of the fort to a winter morning out at Phool Bagh, and by the way, it is built for a Gwalior schedule — bedai and jalebi at seven, tennis at eight, gajak in your pocket for the walk home.
