Slaney Opera has been in consistent form over marathon trips, running third, fourth and third on his last three completions; he got to the front too soon last time and paid for it, but allow for that and the form before his latest blip is solid. Glenmalure Flyer is a point winner who has joined a powerful yard and her stable debut warrants respect if she shows strongly in the market. Henry Box Brown holds a competitive mark on his better form and should not be dismissed. Slaney Opera, better placed with a more patient ride and effective on this ground at this distance, is our selection.
