I'm certain there is a manual on this somewhere. Maybe it's called "The Joy of Setting"? I'm looking for the book with tips on setting indoor climbing simulators.

For climbing simulators, I don't think there's much literature out there, since so few people do it. As for setting in general, here are the two best resources I've come across (in my limited research):

Here is a book in print form for your perusal.

The Art of Course Setting was the book I was thinking of. Thanks Ty, but I think the link is broken.
No specific climbs in mind but when trying to set a certain grade it helps think of real climbs at that grade.
Thanks for the help Earthlings.
