Doug I was using half sloper on 160m for 20 years and it was not bad..I 
worked #300 countries ..BUT
a few years ago I tuned my tower with a shunt and when comparing both 
antennas during many QSOs
a difference was between 1 to 2S for shunt fed tower. The tower has been 
22m high with quite big
hat of TH6DXX and 6 el 6m Yagi  ( that time).
Anyway the tower has been too big for 80m and I still use two half 
slopers for 80m aiming in opposite
directions...I've thought there will be a difference between them but 
its is only about 1 - 2 dB.
Of course I have many radials around but my garden is just 30 x 30 m.
