I'm probably going down the drain with this one thinking he can run as well on dirt.

I've heard that Dynaformer only had four sons run in the Derby:

Barbaro-win
Blumin Affair-3rd
Perfect Drift-3rd
Brilliant Speed another poly/grass type ran a new top of 2.5 at Cd

Have to check the archives to see if he's only had those four run but some pretty good results on the Churchill surface at the distance.

Mom was a dirt/grass sprinter and she produced a dirt winner of the Debutant at CD.

This horse is gonna torture me for the next two weeks.
