Noel Glynn is hopeful his top stayer Becauseicouldntsee will be ready to take up his engagement in the John Smith's Grand National after being handed 10st 8lb for the big race in April.
The eight-year-old gelding suffered a setback after finishing a fine second to the Dermot Weld-trained Majestic Concorde (11st 5lb) in the Paddy Power Chase at Leopardstown in December.
"I'd be happy with that (weight), hopefully we get him there now as we had a setback the other week," said Glynn.
"He's only a week away from going back into work so he's going the right way. We wouldn't have time for a run so it will be straight there."
Irish National winner Bluesea Cracker has 10st 4lb for Aintree and trainer James Motherway feels that is a fair assessment.
He said: "It's a nice racing weight, we can't complain about that. She's due to run in the Bobbyjo Chase at Fairyhouse next week. My owners and myself will probably make a decision after that as to whether she'll go to Aintree or not."
Dessie Hughes, who has Vic Venturi (11st 6lb) and In Compliance (10st 5lb) among the entries, said: "Vic Venturi has got the same weight as last year. We'll have to put up with it, but I'd have liked to see him with a couple of pounds lower. He'll run in the Bobbyjo next Wednesday.
"In Compliance is warming up nicely for it. There's a conditions race coming up for him at Thurles in the next 10 days and he'll probably go there."
Gordon Elliott is looking to get prep runs into Aintree contenders Backstage (10st 12lb) and Nedzer's Return (10st 8lb), but admits Dev (10st) is highly unlikely to make the final field.
He said: "That will do. Backstage won his point-to-point at the weekend. He might have one run under Rules before the National. Nedzer's Return qualifies for the Fox Hunter's as well so I'll have to discuss that with the owners. Dev won't get in."
