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.

You shouldn't handle glass fiber with bare hands either. Ask me how I know it. And your body can't break down glass while it can handle carbon. CF spreads heat better than GF, that may be why GF reinforced filaments don't soften as quickly.
