Turf for many reasons:
1) The "move up" guys are hardly ever a consideration on grass.
2) Turf horses run much more consistent figures.
3) Certain turf courses and rail placements make eliminating outside post positions almost an automatic.
4) The field size of turf races are larger.
5) Larger fields in a horizontal sequence make for better prices.
6) Trainer/jockey profiles and trips (ie.those who save ground) are far more identifiable on grass.
7) Track bias's are more easily identified (ie. lack of rain making for a speed carrying surface)
8) A far smaller pool of top notch grass sires as compared to dirt.

Give me 12-14 horse fields on a firm course all day long!!!!
