Jonbon will be a popular pick as the tapes go up for day two of the Grand National meeting.
Nicky Henderson's hurdler chased home stablemate Constitution Hill at the Cheltenham Festival a couple of weeks ago. That was one of the most impressive performances at the fixture in recent seasons, so Douvan's full-brother sets the standard for his next spring assignment.
Irish trainer Willie Mullins will be hoping to get one of the board with El Fabiolo, before his counterpart Joseph O'Brien sends Fakir D'Oudairies to the Marsh Chase. Both favourites run in the colours of JP McManus, who won last year's Grand National with Minella Times.
