PA6-CF vs PA6-GF - Impact Toughness vs Brittleness

Reading through this thread: https://forum.bambulab.com/t/gf-vs-cf-pros-and-cons/192469

What's the consensus on PA6-GF vs CF?

I'm mostly interested in optimizing Super Safety Components like the lever for impact resistance, but also anti-warping.

Currently using PA6-CF. Having solidish results.

PLA+ lever warped (but didn't break) after 450 rounds of .300blk. Very gassy with a can.

Still need to do more solid testing with PA6-CF.

Both material levers break if I smack em with a mallet on an anvil - but that seems like a shitty metric either way.
