Actually, mostly based on the usual friendly barbs from Pete (N4ZR), I
set up a model for this problem last night and am in process of
running through various guy configurations underneath a C31XR at 65
feet. This is tedious work. (We need somewhere to permanently post
these results other than the archive ... this question just keeps
coming up.) 

Thus far, the worst case discovered (quite some number of common guy
configurations left to go) on 20 meters with the guy starting down 20
feet has .3 amps of current in the guy with full legal power on the
beam, reduces the deep notches in the f/b by 8 db, and reduces the
cross-polarization rejection by over 10 db. All this without any
normally measurable change in forward gain, impedance, or forward
pattern. Stay tuned (Pete ain't gonna let me put this one down without
finishing the paperwork...).
