Topband: Shunt Fed Tower or slopers

[Jorge Diez - CX6VM]

Hi,
will apreciate if someone have experience and comparisons of shunt feed
tower and slopers.
I will rise a 118 feets tower and my first idea was to shunt feed it,
but seems that will work bad if I put yagi´s in the middle and bottom of
the tower.
 
So a friend told me about slopers. Maybe I can put 2 or 3 1/2 wave
slopers in diferent positions with a relay bos to choose between them.
 
Anyone had try and compare them?
 
Thanks in advance
