1. Ace Impact (139p):
   • Unbeaten 3yo, record time in Prix du Jockey Club.
   • Has potential but untested at this trip.
2. Bay Bridge (134):
   • High-class performer, strong form at 1m2f.
   • Unexposed at this trip, strong claims due to previous success in October races.
3. Continuous (133):
   • In excellent form but no horse has ever completed the St Leger/Arc double in the same season.
4. Fantastic Moon (129):
   • Improved recently, holds major claims to become the fourth German-trained winner of the Arc.
   • Better in drying ground conditions.
5. Feed The Flame (130):
   • Progressive, major interest, particularly if the surface is slow.
6. Free Wind (132):
   • Smart mare, needs Frankie Dettori’s magic touch to stand out in this strong field.
7. Hukum (140):
   • Top-class 6yo, strong chance on form but has age stats against him.
8. Place du Carrousel (132):
   • Smart filly, unexposed at this distance, trained by a record eight-time Arc-winning trainer.
9. Simca Mille (131):
   • Acts on soft, consistent and has positive signs to perform well.
10. Through Seven Seas (136):
    • Better than ever at the age of five, gives her nation plausible hopes of finally winning the Arc.
11. Westover (141):
    • Rock-solid record, a respectable contender with a fighting chance.

Conclusion

Analysing the ratings and my notes, Ace Impact and Bay Bridge are prominent contenders due to their unbeaten and high-class performer statuses respectively. Westover also holds significant potential with the highest rating of 141 and a rock-solid record. Hukum despite being older has been consistent and has proven himself as a top-class horse, representing a strong chance based on form.

The horses Fantastic Moon, Feed The Flame, and Through Seven Seas are also notable mentions due to their recent improvement and have major claims or plausible hopes for winning. Place du Carrousel and Simca Mille are also intriguing due to their consistent performances and could possibly upset the field.

Given the summary and analysis of each horse, the logical conclusion would be to focus on Ace Impact, Bay Bridge, and Westover due to their proven records and ratings, but also consider the improving Fantastic Moon and the consistent performers Place du Carrousel and Simca Mille as possible contenders.

At current odds of 16/1 BAY BRIDGE looks a decent each way play. (Ratings are from Timeform)
