Effective immediately, RELAY is considered obsolete.  Digis all over the 
country are switching amazingly rapidly (considering the rancourous 
debate of the last 6-9 months) to the "New Paradigm" standard and are 
disabling both RELAY and dumb WIDE.   The replacement for "RELAY" (i.e. 
for home stations that want to be a first hop into the network) is now 
"WIDE1-1".  

The equivalent of "RELAY, WIDE " (two hops) or "RELAY, WIDE2-2" (three 
hops) in the old order of things  is now    "WIDE1-1, WIDE2-1"   (two 
hops) or  "WIDE1-1, WIDE2-2" (three hops) . 

A home station not capable of true WIDEn-N, that wants to be a digi,  
sets his alias for digipeating to "WIDE1-1" which even a simple dumb TNC 
digi can repeat. Then the second hop "WIDE2-2" can be handled by true 
WIDEn-N digis that can properly decrement the SSID; i.e  
WIDE2-2----->WIDE2-1------WIDE2* 

However, if a true N-n WIDE happens to hear the first hop WIDE1-1 
(instead of a home station), it will repeat it and handle it properly 
with N-n type dupe supression. 


Furthermore, if you are truely " frequently out where there are few or 
no digis in range.", why would the path matter at all?
