Motionbuilder fingers jiggle animation with relation constraints

I’ve been recently playing with relation constraints to see if I could get a bit of a jiggle in my finger animations.

After watching this¬†video from 3d Buzz, I’ve modified their concept based on my needs.

I managed to do it pretty quickly, but I realized that the deformation they get is too toon even with a very low damping value. Although this doesn’t ¬†work for what I do, I think it could be helpful in a previz stage if you have tails or hair. This is what the connections looks like for each finger (click to enlarge the picture) : fingerJiggle

And this is a video demonstrating the result(the value applied to the fingers is quite low, so the effect is subtle but I think still noticeable):
