Hi Paul,
For 160, I would shunt feed the tower and forget slopers.
If you are using a side arm for the low antenna, the face of the tower
opposite the leg with arm and rotator can be shunt fed if you lay out the
wire or pipe carefully to miss the boom and elements.
If you are using a TIC ring rotator, the shunt feed can be insulated and
tucked inside the ring and then brought back out to a "normal" spacing
until it bonds to the tower further up.
UV resistant PVC conduit makes good stand-offs and can be clamped or
strapped to the tower Z- or X-bracing.
Hope this helps,
