How does the Derby picture change with slop?

I would think the Friesan Fire moves up on the LD win in the slop, but what other adjustments do you see out there? How can you even begin to figure out horses like POTN or other synthetic horses in the slop other than Tomlinson ratings? Even though  Friesan Fire did well in the LD slop, that doesn\'t necessarily mean he will do the same in CD slop. I notice this every summer at Saratoga. Saratoga slop seems to be different from other slop.
