Topband: Shunt feeding AB-577/621

[N4ZR]

I have an AB-577 with a C-3E on top, and am interested in the 
possibility of shunt-feeding it for 160 - 100 watts only.  Anyone have 
any experience with doing this?  Are the section-to-section joints 
adequately conductive?  I would plan to use an omega match, because I'm 
guessing it would be well short of a quarter wave.

My other option is an inverted L.  Should I maybe just go ahead with that?
