Why not just take a cup or two, or more, of coffee, sit down and run the AFM analysis ?
Unless you have a fairly critical situation matching a given Type to a runway, the work is not difficult, although often tedious. In the event that you need to run curved departures to keep away from awkward terrain it does get a tad more complex but many airports are fine with a straight ahead departure.
I am never all that happy with endeavouring to fit a visual departure for an OEI takeoff with much tiger terrain as the gradients are far too shallow for any sort of eyeball reliability.
