Topband: Shunt feed vs sloper

[Greg - ZL3IX]

My apologies for revisiting this thread, which was discussed briefly last
month.

I am tempted to try a sloper as the first Topband antenna from my new QTH
here in ZL, as it will be quicker to get going than a shunt feed to my mast,
but there were a couple of negative comments last month.  These were mainly
to the effect that they (slopers) act more like low dipoles.  Can anyone
elaborate on this?  My first intuition is that a sloper should behave in
very similar fashion to an inverted L with the feed at the top of the
vertical section.

My antenna simulation software predicts very little difference in
performance between a sloper and a shunt fed vertical.  Has anyone compared
them on the air?
