"There is pretty heavy rain here at the moment, we wouldn't want it to be too wet, but if it comes up close to a firm track I think he will be pretty competitive," he said earlier in the week.
While the Thorndon Mile remains an option for Shadows Cast next month, Oulaghan doesn't believe the conditions suit his 105 rated gelding, and is favouring an alternative path.
"I'm not quite sure about the Thorndon," he said. "It is set weights and penalties and I am not sure how he is going to get treated.
"We have late nominated him for the Telegraph (Gr.1, 1200m). He could possibly run there and then go to the sprint (Gr.1 BCD Sprint, 1400m) at Waikato, but we are not 100 percent sure yet.
"We will just get through Saturday's race and assess where we go after that."
Meanwhile, in-form Waikato jockey Ryan Elliot hopes to be celebrating his first taste of black-type success for the season when he has Christmas with his family in Levin.
Elliot's big hopes of changing his black-type luck this weekend rest with the rising star Rock On Wood, part-owned and trained by his mother, Leanne Elliot, in the Manawatu Challenge Stakes. Elliot will also ride Concert Hall in the Gr.3 Aberdeen on Broadway Manawatu Cup (2300m).
