Flatter the better for sub surface irrigation. Tile needs to be placed on the contour, not straight lines usually. You need a control structure for every 1-1.5 feet elevation change. More slope = more control structures = more expense. My contact info is in my profile if you would like to talk about it.
Full disclosure. I sell design software, GPS grade control, as well as offer design services.
