1. Saint Sam (FR) – Total: 480.1
   Saint Sam tops the total ratings. This horse tends to race freely, which was a winning tactic when he outclassed two opponents at Tramore last time. This race is more competitive, but Saint Sam has the raw ability to go close if he races more evenly.
2. Effernock Fizz (IRE) – Total: 450.8
   Effernock Fizz ranks second in total ratings. A front-runner who is 1-12 over fences, she came back to form with a solid second in a mares’ handicap at Cheltenham last time. She has won here over hurdles and should run her usual honest race.
3. Fils Doudairies (FR) – Total: 427.7
   Fils Doudairies is third in total ratings. This useful sort has been running mostly over hurdles in the last year, even beating Saint Sam at Leopardstown in March. He did run well over fences over the course and distance last summer, but he has a bit to find with some of these rivals.
4. Busselton (FR) – Total: 417.3
   Busselton is fourth in total ratings. He won the Kerry National last autumn and ran a fine race in the Coral Gold Cup at Newbury. Although he found testing conditions against him at Navan and then in the Irish National, this race should be much more suitable and he holds a solid chance.
5. Telmesomethinggirl (IRE) – Total: 409.2
   Telmesomethinggirl has the fifth-highest total ratings. She is a Grade 2-winning hurdler who hasn’t yet reached that level over fences but was second in a Thurles Listed event in February. However, she fell early at Ayr last time and has to find a bit more today.

Noteworthy mention:

Call Me Lyreen (IRE) – Total: 355.4
Call Me Lyreen won two novices last summer over 2m4f before running well in Grade 3 company. Despite being well beaten in competitive 2m handicaps last twice, returning to this trip can help.

In conclusion, based on their total ratings, Saint Sam, Effernock Fizz, and Fils Doudairies are the top contenders. However, the positive comments on Busselton and Call Me Lyreen suggest they could also perform well, despite their lower total ratings. As always, the actual outcome will depend on the conditions on the day and the performance of the horses.
