Your best bet would be to have a go in a Amazon that is fully poly bushed and see if you like it.
Top wishbones are a must in poly, race cars use nylon in this position. For the panhard rod I do a softer grade poly to help is move as it is supposed to without binding. This binding of the panhard rod is the bump Derek describes and the old way of doing was to use rubber one end and poly the other.
The main thing is to pick what is right for you especially bearing in mind fitting will cost more than either type of bush
