As long as the switching time is manageable, I don't think it makes a 
difference.  Azdens must have been a good buy when the old boys who 
pioneered packet radio in this part of Kansas built their network, 
because several where put into packet service 19-20 or so years ago. 
They use T/R relays and at least one in now in APRS service, relay still 
clicking it's little ole' heart out. At a more relaxed pace now, since 
it no longer passes PBBS traffic. :)
