Don Poli and Kings Palace are the headline acts in an entry of 54 for the RSA Chase at the Cheltenham on 11 March.
Bookmakers are finding it hard to split Willie Mullins-trained Don Poli, who was successful at the Festival last season, and David Pipe's Kings Palace, twice a winner over fences already at Cheltenham.
Don Poli is one of 12 entered by Mullins, along with the likes of Valseur Lido and Vroum Vroum Mag.
English trainer Philip Hobbs has six possibles in the shape of Sausalito Sunrise, Champagne West, Royal Player, If In Doubt, Return Spring and Uncle Jimmy.
Paul Nicholls has four, with Saphir Du Rheu given the option despite being on course to return to hurdles this weekend, along with Ptit Zig, Southfield Theatre and Irish Saint.
The now Sandra-Hughes trained The Tullow Tank, Sego Success, Noel Meade's Apache Stronghold, Coneygree, Le Vent D'Antan, Splash Of Ginge and The Young Master are others of note.
