I think it will depend on what the future plans for SC are.

Santana Strings won a graded stake at the Spa in 05. Annika raced in pretty
hard luck, just missing in some graded stakes.

Not saying this is SC's future, but there is a future out there for a stallion
who wins multiple graded stakes on synthetic as breeders will likely begin to
look to match sires and dams who have shown ability on synthetic surfaces...
