Fair difference in quality between those two ... Sushi Sushi is five times the horse Bus To Harland ever was, in my opinion (not that I would have minded owning him when he won the Gold). Ghadasbest is the only horse from that final that went on to show some promise ... but he's dead now ... poor bugger. Very average bunch in hindsight. Still takes a damn good one to beat them, though, I suppose.
Sushi Sushi was amazing in the Derby ... simply stunning. If he can repeat that effort in NZ, he'll take no end of beating.
