My two cents worth;

1. Pugin - huge weight drop and good form in class races overseas
2. Thong Classic - needs to handle class rise, but last start winner, good form and great weight
3. Distinctly secret - can he possibly have the same 'bad luck' again ? Looks like it's been set for this race alone.

For the trifecta - I'll add Hatha Anna and Media Puzzle.
