I loved Sovereignty but I played Final Gambit in all my exotics since he was the best bred to go 1 1/4.I use Formulator and his sire was 16/62(26%) for his progeny going 1 1/4 or longer (he's out of a Tapit mare, adding stamina on the bottom as well) and his DRF/Tomlinson distance rating was 433, which towered over the rest of the field.
His best path forward may be to become the next Next.
