Willie Mullins expects Hurricane Fly to handle the step back up in trip as he tackles Sunday's Bar One Racing Hatton's Grace Hurdle at Fairyhouse.
The six-year-old was last seen winning the Rabobank Champion Hurdle over two miles at Punchestown in April and his last five runs have been over that trip, but Mullins has decided to step back up to two and a half miles for the first time since he was beaten in a French Grade One in June 2008.
The County Carlow handler said: "He is fine. He is well able for the two miles, four furlongs and we are looking forward to Sunday. He will be joined by Mourad, who is dropping back in trip but should run well."
Solwhit is the only horse to beat Hurricane Fly since that French defeat and finished runner-up at Punchestown.
Trainer Charles Byrnes said: "Solwhit is in good form. He won over this distance in Aintree on good ground so he should be fine over this trip for Sunday."
Voler La Vedette was second in the Morgiana and she is the only mare to take up this Grade One challenge.
"It is very competitive, but she came out of the Morgiana very well," said trainer Colm Murphy.
Noel Meade fields two runners in Donnas Palm and Aitmatov, with the former having finished third behind Solwhit last time.
Meade said: "Donnas Palm has been very consistent but it will be very competitive for him, but he beat Aitmatov in Tipperary in October. Since then, Aitmatov was a bit unlucky when he fell in Navan, where Oscar Dan Dan won. We will probably meet him again so it should be interesting."
Oscar Dan Dan does reoppose and his trainer Tom Mullins said: "We are very happy with him. It is much more competitive this year but his preparation has gone well and with Hurricane Fly and Solwhit involved, it should be a right race on Sunday."
