Rotate extrude along sweep path axis! (wire rope)

Hi,
I have made a wire rope wich follow a spline/sweep function.
But the rope must twist along the sweep axis.
In a straight line I get it done with the helix function, but not with the bend (sp)line in the sweep function.
You can see in the example that i am using a FS to make a helix accros the sweeppath,
but that is not the way because it uses the helix path to sweep and not the origin sweep axis.
Anyone who can help?
Thank you!

It took some doing, but here's my take using a loft with 2 guide curves. The guide curves were created via the Contour Spiral FS.

I juist want a rotation in my sweep profile/path.
Or in other words, that the sweep is going to be rotating along the major/sweep axis.
Or just don't get it? I hope i'm clear!
You can use the spiral FS above to create a curve that rotates around your main sweep path. That curve can then be used as a guide curve, which will rotate your profile sketch as it follows the main sweep path. I believe that's exactly what you're looking for.
But still I ask the question one more time, with a new picture to point out:
As example I want to rotate the highlighted profile along the highlighted axis with a specific rotation/pitch.
With the above mentioned FS i don't get it done... Help?

maybe nice to see the result
I'm trying create an oval ring that looks like twisted 3 strand rope, can you post how you did this?
