Captain Cee Bee, Cornas, French Opera, Gauvain, Golden Silver, I'm So Lucky, J'y Vole, Mad Max, Scotsirish and Sizing Europe complete a select gathering.
Nicholls has taken out Tchico Polos while other notable absentees were Petit Robin and the out-of-sorts pair Forpadydeplasterer and Crack Away Jack.
