Emperor Yohannes IV Palace Museum
Diadem Evolution 16g Tennis String Reel: I do my rounds in here after closing, and I will tell you the thing the daytime visitors never learn: this building is loud when it is empty. Stone underfoot, and every step comes back to you. Emperor Yohannes IV moved his seat to Mekelle in 1881 and built this palace through the 1880s, its construction supervised by the Italian craftsman Giacomo Naretti, who also made the emperor's throne — and the throne is still in here, in the dark, along with the royal furnishings, the ceremonial dress, the arms and the manuscripts of his reign. Yohannes ruled Ethiopia from 1872 to 1889, and it was his choosing this town for a capital that made the modern city exist at all. It is a museum now. I leave one light burning at the far end of the corridor. Not for the throne. For me, walking back.
<p>Mekele sits at 2,254 metres — 7,395 feet — on the Tigray highlands, and anyone who has hit a ball at that altitude knows what thin air does to it. Everything flies. Everything lands two feet longer than you meant.
This is the reel for the player who has decided to solve that problem properly instead of complaining about it, because Diadem Evolution is one of the very few strings on the market that is not a polyester at all.</p>
<p>Evolution is a polyamide monofilament finished with a low-friction silicone-based coating. That matters more than it sounds.
A monofilament gives you the clean, one-piece response and the durability of a poly, while the polyamide itself is a fundamentally softer material — so you get precision and easy power without the board-like impact that puts people off co-poly in the first place. The silicone coating lets the strings slide across each other and snap back, which is where the spin comes from.
Diadem builds it in three gauges: 15L (1.35mm), 16 (1.30mm) and 17 (1.25mm). This is the 16, the middle of the road, the one most club players should be in.</p>
<p>The reel is 660 feet — about 200 metres — which Diadem rates at roughly seventeen to nineteen racquets.
If you restring every three or four weeks, buying the set is simply setting money on fire.
It comes in Natural, Black, Azure Blue and Pink, and it is rated top-tier by the Tennis Industry Association.
Diadem also flag it specifically as a hybrid partner for their shaped strings — run Evolution in the crosses under a shaped poly main and you keep the bite and give your elbow back some of its afternoon.</p>
<p>A word from the highlands, though: at 7,395 feet you will want it a touch tighter than you would string it at sea level, because the air is not going to do you any favours.
You will use this everywhere from a hard court in the shadow of Enda Yesus to the flat ground below the Martyrs Memorial, and by the way — a 660-foot reel is exactly the kind of thing that survives a proper Tigrayan afternoon, the one where the jebena comes out, the coffee is poured three times, and nobody is going anywhere for two hours. Set the reel down. Have the second cup.
It is the middle one that counts.</p>
