Best PC, PAHT-CF or PET-CF support?

Hello everyone,

I recently wanted to print a heavily stressed mechanical part with the Bambu filament, which should consist of PC, PAHT-CF or PET-CF filament. However, after constructing it, I realized that I needed supports. What is the best material to use for these filaments so that they can be easily removed again?

Thank you in advance for the help!
