TGJB,
You can look at that a couple of different ways.
If you have a group of 10 horses, with good dirt speed, but with limited Poly ability, I'll take the proven Poly pedigree most of the time. Why? Because when the majority of the field can't stand up on Poly, and my debut runner is out of a high producing bloodlines, sometimes they don't have to be that good to take the purse. If he catches them on a regular dirt surface, he's apt to get it handed to him, but put him/her on their in-bred preferred surface and it sure brings 'em together.
Just a comment.
