Pedigree Query

Any thoughts on the Giant's Causeways at stud? Those with foals on the ground are Shamardal, Footstepsinthesand, Aragorn, or First Samurai. Noble Causeway is new for this year.

I'm a vet in central KY, and I've seen a bunch of First Sams- all have seemed quite nice. I'm no conformation expert, but Aragorn and Noble Causeway seem lovely, well-balanced types.

I'd appreciate any thoughts!
