The records could continue to tumble for Spirit of Boom this weekend, after the flying Ef Troop (pictured) drew barrier 2 in The Golden Slipper.
It gives Ef Troop, to be ridden by the in-form Jason Collett, a good chance against favourites Sunlight, who has barrier 5 and Written By who drew the 4.
A Group One win in his first season would cap off a brilliant week for the dominant sire, who quinellaed the Jewel with Boomsara and Plumara, and smashed all records at the Magic Millions March Sale.
