Jim,
I don't believe that the DX Sloper would be a good choice for working DX on 
160 meters.
Outside of a contest you may be able to work a bit but you also may 
struggle.

Your 3 section crank-up should be able to be shunt fed on 160. Your antennas 
on the tower will help
lower the frequency, giving it some top-loading.

You will to have all feed lines and control cables coming all the way to the 
ground.

I have some information on Shunt Feeding a tower that I would be happy to 
e-mail to you.
I have been shunt feeding my tower for around 20 years and it does work out 
fine.

Let me know if you would like the information.
