Running CW isn't without pitfalls either, Jerry. Last time I ran 
portable on 160 meters at El Mirage dry lake bed, I kept getting 
RF burns from the rivets that hold the plexiglass finger paddles to 
the metal swing arms on my Bencher keyer paddles (the base of 
my 160 meter vertical was only about 8 feet away). As far as I 
am concerned, however, getting an occassional RF burn still beats
dealing with urban noise levels on 160 meters :)

P.S. Go with the "T" configuration and take some good hi-mu 
ferrites with you for the MIC and Keyers cables.
