SUNLU PA6/12 CF - anyone used with 0.4 nozzle?

Hello,

Have anyone used these filaments already and can tell how was the experience of printing time? Did they work on 0.4 hardened nozzle without issues?

Or should I get 0.6 nozzle just in case?

If you used PA-CF filaments from other brands feedback is also appreciated how they work on 0.4 nozzle
