Now that we have finalized the New n-N pParadigm,
I do not recommend starting a path with RELAY.  Yes,
it has value 1% of the time when you are out of range
of a digi and in range of a HOME RELAY, but the other
99% of the time, that mobile could be generating 2 to 3 times
the number of dupes on every single packet he transmits
when he hits more than one digi.  It just is not worth it.

If there is a black hole, then put a WIDEn-N digi there.
WIDEn-N has perfect dupe elimination and so adding
a digi only adds ONE copy occasionally as opposed to
2 to 3 times as many dupes on every packet from
every mobile...

These fill-in digis should trap then other N-s so as not
to dupe every packet in the area..

So my recopmmendation for the last several weeks now
has been to drop the leading RELAY and just use
WIDE2-2 for local commuting.  WIDE3-3 for travelers
east of the Mississippi and WIDE4-4 for truckers and
long-haul travelers west of the Mississippi except for
obvbious places on the west coast...
