Henry Candy's talented pair Twilight Son and Limato feature in a field of 18 declared for the Darley July Cup at Newmarket on Saturday.
Twilight Son will try to add to his victory in the Diamond Jubilee Stakes at Royal Ascot, while Limato drops back to six furlongs for the first time since finishing second to last year's July Cup hero Muhaarar in the Commonwealth Cup at the 2015 Royal meeting.
Profitable, who was fifth on his only attempt at six so far, was supplemented after winning the King's Stand Stakes.
Clive Cox's crack sprinter has been a revelation this season, having also lifted the Palace House at Newmarket and Haydock's Temple Stakes.
Charlie Hills has two leading contenders in Diamond Jubilee fourth Magical Memory and Cotai Glory, who was only beaten a neck by Profitable in the King's Stand.
Adding an international flavour is Mongolian Saturday, trained in America by Enebish Ganbat, who was ninth in the King's Stand.
Others from the King's Stand are Kevin Ryan's Goken, Charlie Appleby's Jungle Cat and the John Gosden-trained Waady, who were third, fourth and fifth respectively.
Quiet Reflection has gone from strength to strength this campaign, completing a hat-trick of Group-race victories, culminating in the Commonwealth Cup.
Aidan O'Brien will have two runners, Air Force Blue and Washington DC, having taken out Waterloo Bridge, who was the only withdrawal at the 48-hour final declaration stage.
The other Irish-trained hopeful is Eddie Lynam's popular sprinter Sole Power.
Richard Fahey is doubly-represented by Don't Touch and Eastern Impact while Mick Appleby's Danzeno, the David O'Meara-trained Suedois and Arod from Peter Chapple-Hyam's stable make up the list.
