To highlight the quality of the line up, the rank outsider is Rockchase Bullet, who last September started clear favourite for the Derby final, only to suffer terrible luck behind Razldazl George.
Eight months on, the pair clash again, but this time they are joined by Tibetan Skies, Razldazl Will, defending champion Kingo and the hugely progressive Crossfield Star.
The early betting suggests Tibetan Skies will start favourite despite suffering defeat in his semi-final.
There is no doubting his obvious claims, but his style of running may work against him in a contest of this nature.
Known more for his back straight pace and finishing flourish, he could be susceptible to some of his sharper rivals in the early stages.
These include Crossfield Star, Kingo and Rockchase Bullet. Crossfield Star represents Millstreet based handler Brendan O’Shea and he could emerge as the one they all have to beat.
The powerful tracker has improved with each start during the competition, culminating in a superb semi- final success when posting a fastest of the competition 32.36. If repeating that level of form he can race to the biggest success of his career to date.
Tibetan Skies is nominated as the main threat, although Razldazl George and Rockchase Bullet also look capable of getting involved should the big two in the betting make any mistakes.
