Zephlyn arrives here with a progressive profile and a fitness edge that tips the balance in his favour despite sitting a handful of pounds below the top-rated Chief Sunday, who holds the highest rating in the field but may not be as sharp at this stage. Jet Renegade and Jolyjump also warrant respect and will keep the selection honest over this marathon trip at Perth, but neither looks to hold a meaningful advantage when condition and trajectory are factored in. Zephlyn is our selection.
