Dermot Weld's Hidden Universe was the only notable omission from the Betfred Cesarewitch entries at the six-day stage.
The dual-purpose performer won on the level on his final start last season in the Leopardstown November Handicap but he hasn't raced since then.
Weld could still be represented in the contest by Olympiad while all of the other ante-post market leaders stand their ground.
Countrywide Flame, Hurricane Higgins, Montaser, Motivado, I Have A Dream, Repeater and Tominator are all among the 55 entries, of which 34 horses are guaranteed a run.
Aaim To Prosper will have to shoulder top weight of 9st 10lb if he is regain the prize.
Brian Meehan's eight-year-old was a narrow winner of the second leg of the autumn double in 2010 and has since been campaigned exclusively at Listed and Group level.
He could, however, return to handicap company this weekend.
Alhellal (8st 3lb) is an interesting contender for County Kildare handler Maurice Phelan.
The six-year-old has won twice on the all-weather at Dundalk this year and registered his first victory on turf for the campaign when landing the Ulster Derby at Down Royal in June.
Phelan has given his charge a mid-season break and feels he is going into this weekend's race in good order.
He said: "He's fresh and well and he's in good shape.
"The owner is from London and it will be a good opportunity for him to see him as he hasn't been able to get there for any of his wins so far.
"Ideally I'd like a bit of better ground for him, but he showed in Down Royal he does go through soft ground well and he'll have a light weight on Saturday if the top horse stays in.
"I'm not sure whose going to ride him yet."
