Is it best to go with all polygraphite, or a mix of rubber and polygraphite?

Are rubber LCA bushings preferred?

I'm going to be replacing all the bushings on my 71 Duster 340 in the next month and thought I'd ask ahead of time. I'm looking to run some autocross and open track events in the future. I also plan to drive the car a lot.
