Attached Link: Flea Circus - Flea on tightrope

I am modelling a unicycle on a tightrope and have been using Cognito to control the motion via a rack, rocker, gear and cam.

However, I want to rope to dip at the same time as the movement of the cycle.

I tried using Akira Kurozuka's Potentializer but this did not seem to work. I could not perswade the 0 and 100% animation settings to take and I'm not actually sure it would produce quite the right effect.

So does anyone have any suggestions?

Thanks, Andy
