I rate the Derrinstown Stud Derby Trial won by Fascinating Rock as the best and the Lingfield Derby Trial won by Snow Sky (32-pace adjusted 37) as the worst, but I only have a couple of lengths a mile between them.

I would be surprised if Snow Sky proved good enough to win at Epsom. He was always moving well and did score with a bit in hand but needed four cracks with the whip to win the race.
