David Pipe, who saddled Comply Or Die to Randox Health Grand National glory in 2008, is triple-handed this time around with Ramses De Teillee, Daklondike and Vieux Lion Rouge.
"All three of them would prefer the ground on the softer side," he said. "Vieux Lion Rouge and Ramses will run, all being well, but I'm not sure about Daklondike. He's talented but quirky and he would need it soft, whereas the other two would be fine on good to soft.
"We were not sure if he (Ramses) was going to get the trip in the Welsh National, but he got it well and he ran very well at Haydock. While he's only seven, he's been to the Festival, the Welsh National and the Grand National Trial and doesn't seem to be fazed by anything.
"I don't know if he'll get the Grand National trip, but you can say that about a lot of horses. He's not schooled over the National fences yet, we'll school him next week over them, along with Vieux Lion Rouge."
He went on: "Vieux Lion Rouge disappointed us last time, but we've since treated him for ulcers and he now seems to be in good form. He seems to light up for the occasion in the National - he seems to lap up the atmosphere. For some it's a negative, but it's definitely not a negative for Vieux Lion Rouge."
