The claims of ante-post favourite Israr are clear following his course and distance romp of a fortnight ago, but it is a fairly quick turnaround for a three-year-old and preference is for a more battle-hardened campaigner.
The Alan King-trained Tritonic has proved himself a high-class operator under both codes, with three Flat wins supplemented by a trio of victories over hurdles.
Following a five-month break, the five-year-old made a successful return to action when getting the better of the mercurial Goshen on the level at Goodwood four weeks ago.
