Forces fighting each other on particles

I'm trying to accomplish a typical morph between two objects using scattered points and an attractor POP.
All works fine, until I try to add an additional force to the mix to have the particle stream travelling from point A to point B be a bit more irregular.
For example if I add Curl Noise, my particle stream never makes it to the attractor as it seems the noise force takes over.

What is a good way to combine forces but give one force priority over the others?

Thanks

would need to see your hip file to come up with a specific solution, but you could start by dialing down the amplitude of the curl noise, or maybe throw down a VOP POP and tweak the particles' velocity that way.

It's really difficult to balance forces like that. After many failed attempts I resorted to doing straight morphs and then adding noise to the paths of the particles. Looks almost natural and achieves the task every time (being it to morph from one shape to another).

Not necessarily the best example, but can give you as starting point.
