Charlie Appleby is finding it tough to split Master Of The Seas and One Ruler in their respective bids for Qipco 2000 Guineas glory.
The Newmarket handler would love to win the Rowley Mile Classic for the first time on Saturday - and feels his two leading contenders give him a strong chance of doing so.
William Buick has sided with Master Of The Seas following his course-and-distance triumph in the Craven Stakes little over a fortnight ago, leaving James Doyle to pick up the ride on One Ruler on his seasonal reappearance.
"I'm delighted with the way Master Of The Seas has come out of the Craven. He's shown us his wellness during the week - William sat on him on Wednesday and was pleased with him," said Appleby.
"He ticks a lot of the boxes going into the weekend. I couldn't be any happier with him and I'm looking forward to seeing him run.
"We're taking on the same conditions as in the Craven in terms of it's going to be quick ground again. We know he handles that and handles the track, and he saw the trip out well, so I always felt it was going to be hard for William to get off him."
One Ruler has not been seen in competitive action since filling the runner-up spot in the Vertem Futurity Trophy at Doncaster in October, but is reported to be in rude health by his trainer.
Appleby added: "I'm pleased with One Ruler's preparation. He looks great and he's ready.
"James is excited to be riding him. He was in a good position, waiting on William's decision, and he was always going to be happy to jump on either horse.
"They're two different types of horses. Master Of The Seas is a very honest traveller on the bridle, whereas One Ruler is a horse who warms into his race.
"I'm excited to see One Ruler have his first start as a three-year-old. The two horses have got different run styles, but in respect of the calibre of each horse, I think they're hard to split."
Appleby has a third string to his bow in outsider Naval Crown.
The son of Dubawi inflicted a shock defeat on Master Of The Seas in Dubai earlier in the year, before being beaten a neck by the Queen's Tactical on his return to Newmarket in the Free Handicap.
Appleby feels Naval Crown could outrun his odds, saying: "We left him in the Guineas for a reason. Master Of The Seas was entitled to come forward from the run at Meydan and did come forward, but Naval Crown beat him fair and square.
"He's been a rock solid little performer who brings an abundance of experience to the table, and I think the step back up to a mile is going to suit him."
The Charlie Hills-trained Mutasaabeq was mightily impressive when winning a conditions race at the Craven meeting, which ultimately led to connections supplementing for the Guineas earlier this week.
"He seems to have come out of his Newmarket race really well. Jim (Crowley) came and sat on him on Wednesday and said he felt very relaxed and in good shape," said Hills.
"We were trying to nurse him through his career, but his ability has got him where he is now. He's only had two runs, but they've both been at Newmarket - so he's got more experience than most on a course like that.
"It's always encouraging to see horses win the way he did, but he'd done nothing wrong at all in his homework. He was working with the very nice horses at home and worked well with them. Winning by six lengths is nice to see - but did it surprise me? Possibly not.
"It goes without saying he becomes a very valuable proposition should he win a Guineas, being out of a Guineas winner."
Richard Hannon is keen on the chances of Chindit, whose only defeat in five starts came when disappointing in the Dewhurst over seven furlongs here in October.
The Wootton Bassett colt got back on the winning trail on his return in the Greenham Stakes at Newbury a fortnight ago.
"I think he's a Group One horse now - if he wins the Guineas or not - and they are hard to find," said Hannon.
"I feel he's quite intelligent, he knows when he's done enough. What pleased me in the Greenham was it looked like he was only getting going when he crossed the line. He looks like he wants a mile, which is great.
"He's done all his winning on flat tracks like Ascot, Newbury and Doncaster - and this is vastly different. I don't know if he enjoyed the Dewhurst, but I'm fairly sure that was down to the ground.
"The race will have turned him on, I think, just got him going. He travels a lot easier now at home."
