Money came for the chestnut after Kieren Fallon elected to partner her instead of the Nell Gwyn winner Music Show.
Seta was already being talked of as a Guineas prospect when impressing on her debut at the Newmarket July course but was only third to this weekend’s rivals Pollenator and Hibaayeb in the May Hill Stakes at Doncaster.
“She is in very good form and has done well over the winter,” said Cumani.
“It was always the plan to go to the race without a run this year. It’s a wide-open race, I wouldn’t know which one is going to win it, that’s why we are running – to find out.”
Fallon admits he is concerned about ground conditions being too fast for Seta.
“She just doesn’t want it firm because it will take her longer to recover,” said the jockey.
“If you come down the hill at Newmarket on firm ground it can harm them, like what happened to Footstepsinthesand (winner of the 2000 Guineas in 2005).
“He got a really bad bruise and it finished his career. If they do water and we do get a drop of rain it should be beautiful ground and it will suit everybody.”
“Music Show would have to be one of the biggest dangers, with the French filly (Special Duty) obviously although there is a question mark over whether she’ll stay.”
Three-time winner Criquette Head-Maarek trains Special Duty, who shot to the head of the betting after success in the Cheveley Park Stakes, but was beaten on her return in the Prix Imprudence.
Head-Maarek admitted: “We are not sure she will get the mile. From what I have seen so far though she has been doing everything I’ve wanted her to do.
“She was only half-fit for her prep race, you can’t fault her for getting beaten there.
“She needed that race and since then she has come on quite a lot.
“Hopefully we get her covered up, I’m not saying in last, and if she doesn’t pull in the middle of the race she has a good turn of foot and she is capable of running a big race.”
Rumoush, a half-sister to last year’s winner Ghanaati, steps back a furlong in trip having won the Feilden Stakes at Headquarters but trainer Marcus Tregoning does not believe she lacks gears.
“She’s from the Shadwell Foundation mare Height Of Fashion and the bloodline often gets good ones like this,” said the trainer.
“The drop back to a mile will be no problem and I think she goes there with a reasonable chance.
“The big thing with her is her cruising speed, as she showed in the Feilden, and she is from a fantastic family.”
Ryan Moore now rides Music Show, whose trainer Mick Channon is cautious about the ground.
“I wouldn’t like a lot of rain. She loves top of the ground,” said the West Ilsley handler. She is probably as forward as I have had any filly in her coat, but that is because she is ready for it.”
