I think this is one of the hardest races to pick the winner in i have ever seen.
Look at the runners. It includes:

Grey Song - 2nd in Caul. Cup, 5th in Melb. Cup.
Makybe Diva - 1st in Melb. Cup
Mummify - 1st in Caul. Cup
Sound Action - 1st in Ranvet Stks
Grand Zulu - 2nd in Rosehill Guineas
Elvstroem - 1st in Vic. Derby

All of these runs were in the last year alone. Personally i couln't pick a winner, (except a box superfecta lol.) but thats just my opinion
