Sam Turner unearthed a 20/1 winner last week so don't miss his Saturday Channel 4 race guides.
Irish recruit Drumacoo turned his UK debut at Huntingdon into a romp and will be tough to beat if repeating that level of performance, while there should be more progression to come from Vyta Du Roc now he steps up to 3m for the first time.
One Track Mind, a brave winner at Newbury last time, and Silsol who returns to hurdles, have less convictions than At Fishers Cross and could be the chief threats, although Deputy Dan exceeded expectations behind Thistlecrack at Newbury before being beaten 20l by the same rival last time at Ascot.
Montdragon and Different Gravy are two other lightly-raced hurdlers from top yards who deserve respect, but at his double figure price with yard back among the winners, Sirabad gains the nod.
Silviniaco Conti has been tough to train and sports the blinkers for the first time which could be the catalyst to a more enthusiastic showing, however he takes on one or two more naturally speedy rivals so may be vulnerable.
Backing Flemenstar obviously comes with risks attached given he has always seemed happier at 2m, however he posted another fine effort at Punchestown behind Felix Yonger in an extremely strong time and he looks worth risking in a race where there looks doubts over the main protagonists. His association with Andrew Lynch has yielded figures of 121111111323112, while his record when returning to the track between 14 and 30 days reads an impressive six wins from eight starts (11113141).
