'It depends'....
Sequence of routers (but not tramsports) matters. Very much so.
If you are *certain* that no other router can (ever) match and grab the
traffic, AND that your manualroute will not (ever) grab traffic you do
not intend for it to process, then it matters little.
More realistically, you will want to arrange your routers such that:
A) Common case does not intercept 'edge' case, nor the reverse.
Sometimes harder than it looks.
B) Most-frequently matched routers preceed less-common cases (subject to
the above). That simply to shorten the 'router walk' and economize on
resources over months and years of running.
The default sequence is 'general purpose' sane, so place it where those
factors 'look right', then TEST thoroughly, use bespoke 'dummy' accounts
first, 'real' ones once satisfied.
Otherwise, 'edge' cases tend to leave teeth marks on the anatomy...
sometimes at once, other times not until weeks or months after you have
forgotten about the issue.
