If I have 5 images A B C D E that I wish to line up, am I better making ?
A-B, B-C, C-D, D-E
or
A-B, A-C, A-D, A-E
or
A-C, B-C, C-D, D-E
pairs?

"Line" control points are evaluated (optimized) by comparing the a line drawn by
the first two points and the distance all other points are from that line. So I
always place the first two points at the ends of the line. The rest of the
points for that line makes no difference how they are added.
So if I had multiple straight lines going though multiple images I would
probably do.
A-E, B-D, C-C
If does not matter how the "line" points are added to B, C, D
Important: Horizontal, vertical, and straight lines are evaluated on their
output projection.
