Kingman and Toormore are among 27 horses in contention for the Qipco 2000 Guineas at Newmarket on Saturday week following the latest forfeit stage.
The John Gosden-trained Kingman rocketed to the top of ante-posts lists following a breathtaking display in the Greenham Stakes at Newbury, while Richard Hannon's Toormore is also unbeaten following a determined effort in Newmarket's Craven.
Roger Varian remains delighted with his Racing Post Trophy hero Kingston Hill ahead of his seasonal reappearance in the colts' Classic.
The trainer said: "He looks terrific. We took him to Newbury for a gallop a couple of Sundays ago and he went very well.
"Kingston Hill is a clear-winded horse who has done plenty of work so he will be ready on the day.
"I couldn't be more pleased with him. Good ground would be perfectly fine - he might even be better on it - and, although I would review his participation in the Guineas if the ground came up very quick, I think that is pretty unlikely."
There are nine international contenders remaining in the 2000 Guineas, notably Aidan O'Brien's duo Australia and War Command from Ireland.
Charm Spirit from France and Noozhoh Canarias from Spain are also down to run, while True Story, a most impressive scorer at last week's two-day Craven Meeting, is one of three representatives from the Godolphin stable.
There are 33 fillies still remaining in the QIPCO 1000 Guineas a week on Sunday including Nell Gwyn winner Sandiva and Fred Darling heroine J Wonder.
Ante-post favourite Rizeena also features along with eight overseas-trained contenders headed by O'Brien's Tapestry, John Oxx's My Titania and Andre Fabre's Miss France.
Varian has left Princess Noor and Hadaatha in and said: "Princess Noor is doing well and her work has been good.
"She has a stamina question to answer as all her form last year was over six furlongs, but she is quite relaxed - which should help her get the mile.
"She had a very high level of form as a two-year-old so is definitely entitled to take her chance.
"If she gets the mile she will run a big race.
"Hadaatha has come out of last week's Newmarket maiden race victory well.
"Although we have not 100 per cent ruled the Guineas out, I think that it may come too soon for her.
"She will do a piece of work this weekend and we will decide afterwards."
