Main mission Vic Derby currently 40/1 EW WA fixed odds.

Chances of both (like a lot of early 3YO staying races) will depend on the depth of staying talent they encounter.

Imaginaire is bred to stay (as already mentioned on this thread a number of times).

Destiny's Day has run on well both starts and his last start win was full of merit, did not have the best of luck in running. His dad Montjeu won a lot group races between 1600m to 2400m including the French and Irish Derbies. So DD is also bred to stay.
