......, then string up the rod with flyline
and put enough pull on the line to put a bend in the rod. Then you
study the guides, looking for, hell, i don't know, things that don't
look right....

As I understand it (or perhaps misunderstand it), the angles that the
line bends when it goes through each guide should all be equal.

(I apologize for writing something as awkward as "angles that the line
bends," but at the moment, I can't think of a more elegant way to say
it. Somehow,"angle of dangle" doesn't seem appropriate.)
