Wilwood kit vs Dr Diff Wilwood kit, help??

Oooh crossdrilled rotors .Kewl!
Does anyone hate crossdrilled rotors as much as I do?
Every race car I ever worked on with steel rotors and crossdrilled holes would run a very short duration & have micro cracks radiating from the holes. For this reason I prefer slotted w/no crossdrill & I'd be willing to bet you'd have to order them special, IF they'll even sell them that way.
But they look like you know what you're doing, so they're cool!
